Preface

The Information and Communication Technology Agency of Sri Lanka (ICTA) has identified the enabling
of ICT in local languages, Sinhala and Tamil, as a priority area in the e-Sri Lanka initiative. ICTA is
promoting the use of ICT in Sinhala and Tamil, and is addressing issues relating to enabling ICT in local
languages such as the relevant standards with regard to encoding, keyboard layouts, collation
sequences and also the availability of standards based (Unicode compliant) fonts.

With the advent word processing and desktop publishing there was an increase in the development of
English fonts. Now there is a wide choice with regard to standards based fonts in English. But this is not
so for Unicode compliant Sinhala fonts. Therefore ICTA has been promoting the development of
Unicode compliant local language fonts. Several Unicode fonts such as MalithWeb, Dinamina were
developed. Subsequently ICTA ensured the development of the Unicode Sinhala font Bhashitha and the
Unicode Tamil font Sri Tamil. The font rules of these two fonts are given free to font developers.

But one of the impediments encountered in getting the fonts developed was that there was a dearth of
proficient font developers, and it was necessary to get developers to develop Unicode compliant fonts.
There was a necessity to develop awareness among font developers on how to create good quality
standards based fonts. The necessity to develop awareness encompassed both the technical area
covering font rules, and also designing.

In view of this ICTA, in partnership with the University of Colombo School of Computing (UCSC)
implemented a training program with the objective of providing font developers with the knowledge
and expertise on how to develop standards based, aesthetically correct local language fonts of good
quality, in order to upgrade the general level of skill and knowledge in this area.

The training was conducted at the UCSC and was in the form of interactive workshops. An eminent
panel of resource persons conducted the training. Participants were required to give a commitment
that they would develop a portfolio of at least two glyphs.

Those who followed the training program are now able to develop Sinhala fonts. Several stylized Sinhala
fonts have been developed by the trainees, and the proceedings of the training have been compiled into
this book. This book fills a lacuna which has been felt in the font industry. It is expected that local
language font developers will find this useful.

Introduction

Sinhala was encoded in Unicode in the latter part of 1990s. The encoding process was initially
spearheaded by the Council for Information Technology (CINTEC), by Prof. V.K. Samaranayake, Chairman
of CINTEC and the founder director of University of Colombo School of Computing (UCSC), Prof. J. B.
Disanayaka, who was Sri Lanka’s Ambassador to Thailand and Professor emeritus of Sinhala, University
of Colombo, and also Mr. Nandadsara of UCSC. Although the encoding was carried out in the 1990s, it
took another seven years for a proper implementation of Sinhala Unicode to take place.

The Information and Communication Technology Agency of Sri Lanka (ICTA) operational from July 2003,
realized the importance of the local language initiative and agreed that this area should be taken over,
given priority and promoted.

The objective was to ensure that the benefits of ICT should be taken to the population in Sri Lanka most
of whom, if given a choice, would prefer to use ICT in Sinhala or Tamil. Hence the Local Language
Working group the members of which had with expertise and experience in this area was established.

Thereafter, joint research was carried out into Sinhala Unicode by UCSC and the Department of
Computer Science and Engineering of the University of Moratuwa, under the aegis of ICTA. The input
method for Sinhala Unicode was standardized in 2004 by the Sri Lanka Standards Institution (SLSI) as the
Sri Lanka Standard Sinhala Character Code for Information Interchange SLS 1134 : 2004. The main
author of this standardization document was Prof. Gihan Dias and the other two main researchers
during this phase of the Sinhala Unicode implementation were Dr. Ruvan Weerasinghe and Mr. Harsha
Wijayawardhana, both from UCSC.

With the release of Uniscribe (Shaping engine) of Microsoft in 2003-5, Microsoft introduced Iskoola
Potha. ICTA’s Local Language Initiative, under the direction of Prof. Gihan Dias spearheaded the
development of Unicode compliant Sinhala fonts. ICTA held several awareness sessions on Unicode for
Font Developers. During this period, Mr. Anura Tissera formerly of the Associated Newspapers of Sri
Lanka (Lake House) created the “Dinamina” font. The development of several other fonts followed:
Prof. Gihan Dias, Mr. Harsha Wijayawardhana, and the Linux User Group released Malithi, Sarasavi
(Unicode) and LKLUG font respectively. All these fonts were results of research carried out into Unicode
font creation in Sinhala and Tamil.

Mr. Sinnathambi Shanmugarajah thereafter developed a Sinhala “kit” incorporating standard Sinhala
fonts, keyboard driver and installation instructions, which was made available free of charge on the site
www.fonts.lk.

With the wider use of Sinhala and Tamil Unicode, the dearth of Sinhala and Tamil Unicode fonts had
been identified as a major issue and as an obstacle for popularization of Sinhala and Tamil Unicode
content. In order to remedy the above, ICTA initiated several projects.

Thereafter ICTA ensured the development of the Unicode Sinhala font Bhashitha. The objectives were
to make available freely correct Sinhala SLS 1134 : 2004 compliant font rules, to generate accurate
Sinhala documents with the use of full complement of characters facilitated in the standard SLS 1134 :
2004, to discourage the use of legacy Fonts that are not SLS 1134 : 2004 compliant and to enable Old
Sinhala / Pali (written in Sinhala script) books and content to be published on the Internet for
worldwide audiences.. Ms. Dineesha Ediriweera and Mr. E.D. Pemasiri developed the font rules and the
font glyphs respectively for the Bhashitha font.

This training program was held to train font developers, on developing Unicode compliant, aesthetically
correct fonts of good quality. Several Unicode Sinhala fonts have been developed as a result of the
training – Puskola Potha, NYH, Warna, and SS-Sulakna, Winnie, Winnie1 designed by Ms. Nirmali
Allahendra, Mr. Nirmala Handapangoda, Mr. Warna Somaratne, Mr. Sushiksitha Sasirichandra and Mr.
Mr. Winnie Hettigoda.

For this training program held at the UCSC, most of the pioneers in Sri Lanka’s Unicode research in
Sinhala and Tamil came together and it was coordinated at ICTA by Ms. Aruni Goonetilleke, program
manager of ICTA.

Chapter One
WHAT IS UNICODE?
Dr. Ruvan Weerasinghe, University of Colombo School of Computing

Computers store data as 1 and 0 and a decimal number expressed in 1 and 0 is known as a binary number.
Characters are also stored as binary numbers in computers. The Latin script was the original script which
was used in handling data in computers and subsequently the need for storing data in other languages
became one of the major researches prior to the 1990s. Although the problem was solved in the pre-
Unicode era by mapping numbers of English characters in a font to characters of another language
(shapes of English characters were replaced by character shapes of another language), the need arose for
storing data in different languages in a single document. When a document was prepared in two different
languages, only one language could be viewed and the other appeared as garbage. Also in data
transmission from one computer to another, it was essential to send the font which was used, with the
document. Sorting of data was not possible since data was sorted according to English or any other
Roman Script based language in the pre-Unicode era. By the early 1990s, Unicode was suggested as a
possible solution to the above problems.

in ASCII Fonts

Unicode provides a unique number for every atomic character in different languages. This number is
usually stored as two bytes inside the computer. The first byte of the two byte code of a character
provides language identification and the second byte gives character identification in that language.
Unicode is designed to work independent of platform and of the application program which uses Unicode
font. At present, more than fifty unique scripts have been encoded in Unicode.

i. The Unicode consortium

The Unicode consortium is a non-profit organization based in California, USA to develop, extend and
promote the use of the Unicode Standard in the world. The membership of the Unicode consortium
includes countries, large corporations and organizations in the computer and information processing
industry. The consortium is financially supported solely by membership fees at present.

ii. Sinhala Unicode

Computer literacy in Sri Lanka has overtaken English literacy and at present it is at 10%. It is now widely
believed that the Computer literacy is at 20-25% in Sri Lanka. Localization had been a priority in Sri
Lanka since the 1980s and Sinhala was encoded in Unicode in 1997 although the implementation of
Sinhala Unicode was not initiated until 2003 in earnest. Sinhala, unlike English is categorized under
complex scripts. Sinhala belongs also to Phonetical languages or sound based languages and all Indic
languages are categorized under this category. Sinhala, like other Indic languages, can make a single
glyph with a consonant and vowel modifier. A glyph, always in the English language has a single code
point and represents a single character. Unlike English, Sinhala glyphs can either have a single code point
or a number or many code points or numbers.

In order for Sinhala Unicode to function properly, it requires the following:

1. Sinhala Unicode font
2. Shaping Engine such as Uniscribe for MS Windows, Pango Linux etc.
3. Sinhala Unicode Keyboard driver for input and this is not necessarily required for Unicode text

rendering.

THE DEVELOPMENT OF THE SINHALA SCRIPT

AND THE CHARACTERISTICS OF THE LETTERS

Professor Rohini Paranavitana
Department of Sinhala, University of Colombo.

Language is the basis of human communication and is an essential feature of human life and
differentiates human beings from other living beings. Language thus interacts with every aspect
of human life and enables one to exchange human thoughts with one another. As it is difficult to
remember everything, which we have spoken, heard or thought, it is necessary to record them in
writing, not only for the benefit of oneself but for the benefit of others in society and to transmit
them further for future generations. Hence, writing paves way for communication with people
far in place and time. An alphabet is a set of standardized visual symbols, used to record/write
the sounds of a language. The sounds and their symbols thus produce a perfect language.
Therefore, the relationship between speech and written symbols is similar to the relationship
between a human and his photograph.

Fig 1:- Brahmi Script

Sinhala is the language spoken by the Sinhalese
who constitute 75% of the island‟s population. The
earliest extant Sinhala writings belong to the 3rd
century B.C. These writings are to be found in
inscriptions in rock caves of Mihintale, situated 8
kilometers from the ancient city of Anuradhapura.
The earliest inscription there refers to a king by the
name of Uttiya, the younger brother of King
Devanampiya Tissa, who reigned in Sri Lanka in the
3rd century, B.C. These are called Brahmi
inscriptions, because they are written in the script
known as Brahmi. With the introduction of
Buddhism to the island in the 2nd century B.C. by
Arhant Mahinda, who was the son of Emperor Asoka
in India, the inhabitants in the island became
devotees of the Buddhism.

Page | 10

Fig 2:-Inscriptions (3rd century BCE-2nd century CE)

The primary task of the laymen was to provide food, lodging and medicine to the Buddhist
monks. The content of the most of these inscriptions are records of the donations made to the
Buddhist monks by their devotees. The names of the donors have been inscribed on the drip
ledges of the caves, and were not only the names of the royal family but were also names of
people from all walks of life. . The Buddhist monks lead a simple life and they preferred to take
their shelter in the caves, which were prepared by the devotees to suit their austere life. The
earliest written records existing in the island today cannot be assigned to a period earlier than the
3rd century B.C. Archaeologists have argued with evidence that this script was brought from
India even before the arrival of Arhant Mahinda. It has been found, that the earliest examples of
Brahmi writings extant in the island contain some peculiar features, which are not noticed in the
inscriptions of Emperor Asoka of India, who had extensively used Brahmi script to inscribe his
discourses.1

The earlier inscriptions written briefly became longer and complicated with the development of
the subject matter recorded in them such as regulations and administrative matters relating to the
monasteries. As a result the Sri Lankan alphabet too began to invent its own features by the 4th
century A.D. Over the ages, it accumulated new features and by the 8th century the long and
short æ and nasal ng, nd, mb became evident in the Sinhala alphabet making them unique.2 The
vowel sound æ had a short and a long vowel pronunciation, short æ being similar to the sound
emanated when pronouncing English at and the long æ being similar to English ant.

The Aryan settlers, who migrated to Sri Lanka from time to time from India, brought with them
the knowledge and methods of writing, which were in use in their motherland at that time. At the
time of the arrival of Arhant Mahinda, the language of the island had attained a developed state
for expressing a philosophy of highly complex thought to be given to people by way of free
expression. Had the language not been developed, it would have been impossible to write
commentaries for explaining the tenets of Buddhism during the lifetime of Arhant Mahinda.

The Pali Tripitaka and its commentaries were translated into Sinhala, the language of the
inhabitants of the island. It is these commentaries, which were later translated into Pali by
Buddhaghosha Thera, who arrived in Sri Lanka from South India in search of the Buddhist
doctrine in the 5th century CE.3

There are hundreds of inscriptions representing the development of the Sinhala script which
belong to every half a century of the Anuradhapura and Polonnaruwa periods. This unbroken
series of epigraphic records indicates the evolution of the Sinhala Script. In the beginning, the
subject matter and the number of letters used in the inscriptions were limited. In the evolution of
the Sinhala Brahmi script in Sri Lanka several important stages have been mentioned. The first
stage consists of the period from 3rd century BCE to the end of the 4th century CE. Subsequently
at the second stage the letters began to take a slightly a circular shape. In the eighth century, it
came under the influence of the South Indian Pallava Grantha script which influenced very
much in taking the Sinhala script towards the modern form.4

Fig 3:- Pallava Sinhala akuru
Granthakshara( 7-8 A.D.) (8 century A.D.)

The types of material used for writing also had a tremendous impact on the evolution of the
script. In the beginning stone would have been the most popular material on which the
inscriptions were engraved. Stone was replaced by palm leaves by the eighth century.

The texture of this material helped very much to move the stylus to write letters in a more
circular manner in order to avoid the leaf being damaged by angular strokes. Sinhala was in use
for writing various subjects with the influence from Pali and Sanskrit languages. In Sri Lanka,
the compilation of books witnesses their origins from very early times. It has been suggested by
S. Paranavitana that writing on palm leaves commenced in the 8th century CE, but P. E. E.
Fernando holds the view that the practice of using palm leaves as writing material was known in
Sri Lanka even in the 5th century the latest.5

When writing on palm leaves became popular, the books transmitted orally came to be written
down on palm leaves . Henceforth, every composition except epigraphic records was written on
palm leaves. The use of palm leaf as the material of writing was a great impetus for the
improvement of literature as well as for the spread of learning. The palm leaf manuscripts
succumbed to various forces of destruction and the oldest manuscripts available today are
believed to have belonged to 13th century CE (Dambadeniya period).6 One of the manuscripts,
the Cullavagga, is deposited in the Colombo Museum Library and the other manuscript, the
Visuddhimagga tika, is available at the Peradeniya University Library.

The majority of the manuscripts belong to the period of King Kirti Sri Rajasingha, who reigned
in Kandy in the 18th century. As a result of the Buddhist and literary renaissance headed by
venerable Weliwita Sri Saranankara thero, majority of the manuscripts, which were deposited in
the temple libraries were copied and distributed among temples.

Printing of Sinhala books commenced in 1737 during the Dutch administration of the littoral of
the island. A book on the grammar of the Sinhala language was published in Dutch by Johannes
Ruell and was printed in Holland in 1707, even before the printing was introduced in the island.
It contains examples from Sinhala language for various grammatical rules and those examples
were printed in Sinhala characters.7 This can be presumed as the first time that Sinhala characters
were printed in a book.

It can be concluded that Sinhala printing was first introduced in Sri Lanka in 1737 during the
time of the Dutch Governor, Gustaaf Willem Baron van Imhoff. Sinhala letters, which were
being written on palm leaves thus moved on to being printed on paper. The first book published
in Sri Lanka is a prayer book in Sinhala.8 It was known as the Lord‟s Prayer. The proclamations
of the Dutch Government called Plakaats were also printed in Sinhala, Tamil and Dutch, at the
new press introduced by them. These Sinhala characters for printing were designed and cut on
wood by a Dutch technician, Gabriel Schade9. There, the printers have strictly followed the
contemporary writing style extant on palm leaves without much of the standardized
punctuations, separations of words, etc. The first printing press with Sinhala types had remained
the only press for many years that followed. Several other printing presses were established by
the Christian missionary societies during the early 19th century. Christian books, including the
Sinhala. versions began to be published.

Buddhists too started their own printing presses and published newspapers and journals in
which they printed extracts from classical Sinhala texts among other things. These printers took
the initiative of publishing the texts as part of their religious and nationalist movements. As the
palm leaf writers were not in the habit of using many punctuation marks and separation of words,
the modern text editors faced the difficult task of changing their system of writing. The script of
the palm leaf manuscripts had peculiarities in writings particularly in the conjunct consonants,
double consonants with repha and aspirates, half nasals, etc. With the introduction of the printing
press the letters became still more circular.

Fig 9 -: Sizes of letters

The initial components of the medial letters are written in a small phase over the middle phase.
The strokes that come after and before the consonants are written in the middle phase. The initial
component of the letter ෆ begins at the lowest point of the middle phase. The stroke which
denote උ vowel is written below the middle phase in ග, ඟ, ශ, භ and ක

There are two kinds of ascending letters, namely, letters without
a stroke at the top and the letters with a stroke at the top. The
letters of the first category are little shorter than the second

category. ට ධි ව ම් ඔ ඕ බ

The ඣ letter is formed combining of
two letters, one medial letter and an
ascending letter. The ළු which

represent cerebral ළ and vowel sound
උ is also an ascending letter. The
descending letters are written in the
middle phase and spreads to the lower
phase.

Fig 10 -: Ascending letters

Fig 11 -: Descending letters

ඤ and ඥ are written with the combination of a medial letter and descending letter. All the
medial strokes which combine with the descending letters are written in the same way as they are
written with the medial letters.

The strokes that are written as a combination with consonants to represent a vowel sound can be
divided in to three categories. The strokes are smaller than the letters. The medial strokes can

be written in the same height as the medial letters දා, දැ, දෑ, දෘ, ද , දදෞ. The strokes are
written usually after the letters except the (ද ) kombuwa. It comes before the letter. The

yansaya ( ) that represents a consonant sound is also categorized as a medial stroke.
Traditionally the strokes that combine with the ද letter are written on the lower phase. It is more logical

writing them on the middle phase. The ර letter with ඇ vowel sound is written with an ascending
stroke.

Page | 18

The ispilla that combines with the aelapilla denotes the ඕ vowel sound as in දගෝ and දවෝ
letters. Though there is a slightest difference between uspilla and udupilla it should be clearly
understood and written. The aelapilla is combined with ර as an ascending stroke but it combines

with other letters as an medial stroke රෑ, කෑ.
The strokes that are written on the lower phase are descending strokes. Most of them denote the

u vowel sound as in කු, තු, සු, වු. The rakaaraansaya which represents the consonant
sound ර is also a descending stroke as in ක්රs, ශ්රn. There are two kinds of descending strokes. Kon

paapilla and vak paapilla. Kon paapilla is the stroke that is written with the consonant ස, ද, ව;
සු, දු, වු. Vak paapilla combines with the medial letters, ක, ශ, ඟ, ත, භ. These

descending strokes are not used to denote the ර letter combine with the උ vowel sound. As a
special case the aelapilla is written with ර to denote that sound. These strokes that denote උ

sound are not used with the cerebral ළ either. The ascending letter ළු is written to denote that
sound. A long aedapilla is used to denote the long ළූ sound. When the descending strokes are
combine with ද (da) letter the ending component of that letter will be deleted as in ද, දු, ද , ද්ර ,
දෘ (da, du,dya, dra, dru).

Chapter Three
TAMIL SCRIPT

The Tamil language belongs to the Dravidian Family of languages. Tamil is one of the oldest languages
in the Indian Subcontinent with a recorded history of two millennia. Tamil is the official language of the
state of Tamil Nadu, India and is one of the twenty two scheduled languages of India. Tamil is spoken
widely in India, Sri Lanka and is an official language in Sri Lanka and Singapore. The Tamil language
was the first language to be declared as a classical language by the government of India in 2004. Tamil is
spoken by sizable minority populations in Mauritius, West Indies and Malaysia and it is commonly
spoken by many emigrant communities worldwide. Tamil literature has a long history of two thousand
years and the earliest period of Tamil literature which was known as “Sangam” period began in 300BCE
and ended in 300 CE. The earliest epigraphic evidence of Tamil goes back to 3rd century BCE and Tamil
inscriptions from 1st BCE to 1 CE were found in Egypt and Thailand.

The closest relative to Tamil language is Malayalam and until ninth century, Malayalam remained as a
dialect of Tamil and the complete separation of Malayalam from Tamil to a separate language was not
completed until 13th-14th century. Tamil descended from Proto Dravidian which was spoken in 3rd
millennium BCE. Scholars believe that Proto Dravidian was spoken in the southern region of India
around Godavari river basin. It is believed that in 3rd century BCE, Proto Dravidian would have given rise
to Proto Tamil. The attested history of Tamil categorized into three periods: Old Tamil (300 BCE –
700CE), Middle Tamil (700 – 1600), and Modern Tamil (1600 –Modern Present).

Tamil is written by using a script which known as Vetteluttu. Some of the earliest epigraphy of Tamil
Scripts points that it had evolved from Southern Brahmi Script. Old inscriptions of Tamil found in the
early period were short and were discovered in caves and on pottery. The longest text in old Tamil is
known as Tollkappiyam, which was an early work of grammar and poetry , the oldest layer of this
inscription may be going back to 1 BCE. A collection of literary work in Old Tamil had also survived
which included two thousand poems and this collection is collectively known as Sangam Literature which
could be dated back to 1st CE to 5th CE. Other literary works include Cilappatikaram and Manimekali.
Especially Manimekalai is set in South India and in Jaffna Peninsula Sri Lanka. Subsequently Tamil
script was influenced by Pallava Grantha. Grantha,‟ book‟ in Sanskrit was a script which was used for
writing Sanskrit in the region where Dravidian was prevalent. Grantha had letters which represented
sounds which were not in Tamil. The present look of the Tamil Script would have emerged in 8th Century
CE and it remained static since then.

Tamil Script has 12 vowels and 18 consonants and a special character which is known as Aytam. The
combinations of vowels and consonants make 216 combinations and this number is the smallest
combinations, which is found in Indic Languages. Like other Indian Languages, all consonants carry an
invisible Vowel „a‟ and dead consonant or pure sound is produced by placing a visible virama which is
known as a „Puli‟.

UNICODE ENCODING OF SINHALA

Prof. Gihan Dias
University of Moratuwa

Introduction and background

The need to support Sinhala on computers was identified some time back. In 1980‟s the main
focus was on a hardware based solution. Later many Sinhala Fonts were developed.
Eg: DL-Anurada,DL-Lihini,DL-Manel aputa,kaputadotcom,MalithiWeb,madhura,Thibus29STru

When using a keyboard, different layouts were used:.
- Phonetic keyboard: In this layout the characters represent the sounds of spoken language.

e.g.: „k‟ is used for „ඕ‟
- Wijesekara Keyboard: This keyboard is based on the Sinhala typewriter keyboard

Page | 30

-

When using the above keyboards several issues were identified. There was a problem of
representing some characters such as ඕු, ළු, රැ, රි, දු, ත, ද, ඤ, ම.

To ensure that standards are followed regarding computing in Sinhala and Tamil, CINTEC
established the Committee for Sinhala and Tamil in Computer technology in 1985.The
Committee agreed on a unique Sinhala alphabet and an alphabetical order. At first the encoding
was based on the ISCII (Indian Standard Code for Information Interchange) and later it was
expanded to support Unicode. In 1997 it was adopted by Unicode with some minor
modifications.

SLS1134 : 2011 Sri Lanka Sinhala Character Code for Information Interchange

The current standard which provides coding of the set of Sinhala characters for use in ICT is the
Sri Lanka Sinhala Character Code for Information Interchange SLS 1134 : 2011. This new
version provides encoding for Sinhala numerals.

Sinhala Language and Alphabet

Sinhala Script

The Sinhala Language belongs to Indic family of languages. In the Sinhala script each letter may
consist of a consonant and a vowel and so is called an “abugida”. Each syllable unit is an
individual visual unit or glyph. Two glyphs can tie up and form conjunct consonants which are
called “බැඳි අකුරු - Bandi akuru” in Sinhala. Sorting words which are written in different styles
(Conjunct consonants as opposed to ordinary writing) should be done according to the sorting
rules of the Sinhala language.

Sinhala Alphabet
Sinhala Alphabet consists of 59 based letters. It includes

•   16 vowels
  

•   41 consonants
  

•   2 semi-consonants

INTRODUCTION TO FONTS

by Harsha Wijayawardhana,
Theekshana

1. Introduction

In typography, a font is regarded as a set of characters (it is usually a whole of Alphabet) of a
single size and style of a particular typeface. A typeface can include one or many fonts with a
single style or stylistic unity, but can vary in sizes with a coordinated set of glyphs which
represent characters, symbols punctuation, and numerals. The word „glyph‟ plays a major role in
a font and a typeface where a glyph can be defined as an element of writing and is a vague term
in typography especially in multi lingual fonts. In Indic scripts, a set of conjunct characters or
letters (conjunction of atomic characters) can make a single glyph. Prior to the advent of desktop
publishing, a font and a typeface had very distinct meanings. In those days, a font was a member
of a family of fonts whereas a typeface was a family of fonts with a similar visual appearance
with specific sizes. An example, a member of 6 point Roman Sans Serif bold or italic is a font
and a Roman Sans Serif is a typeface. The size of a font is measured in points and in the pre
computer age, a particular point size was a different font, the distinction of which, in the era of
computer desktop publishing where size is easily scalable in outline-fonts, has become obsolete.
In other words, a single font is scalable to any point size.

2. Font Sizes

A point size of a font was mentioned in the previous section and a point had been defined
differently in different periods. In the present day of desktop publishing age, the most popular
way of defining a point of a font or typeface is as a Desktop Publishing unit, which is 1/72 of an
inch or 0.0139 in/0.35mm. Specified size of the Desktop Publishing Unit is set to scale size of an
em-square which is an invisible box, the height of which is typically bit larger than distance from
the tallest ascender to lowest descender. Measurements of non typographic units (meter, feet, and
inches) are given as Caps height or height of Capital Letters.

3. Digital fonts

Digital fonts can be divided into two main categories: Bitmap fonts and outline fonts. Bitmap
fonts store an image of character or a letter as a Bitmap whereas, in an outline font, an image of a
character or a letter is stored as mathematical descriptions of lines or curves. Outlines fonts are
also known as Vector Fonts. When outlines fonts are used, Rasterizing routines are carried out
either by application software, Operating System or printers and outlines of characters in a font
are rendered according to vector interpretations which are stored in the font.

Digital fonts also contain information on font metrics for composition as well as information on
kerning pairs. Common fonts formats include METAFONT, PostScript Type1, True Type Fonts
and Open Type fonts. Digital fonts are created using font editors such as Fontlab and Fontforge.

Typefaces are divided into two main categories: Serif and Sans serif. Serifs are a decorative type
of typeface where a serif font comprises small features at the end of strokes within a letter. Fonts
which do not have these small features are known as Sans Serif. „Sans‟ means „Without‟ in
French. In other words Sans Serif means „without serif‟. Usually, printed works such as
newspapers and books are printed with Serif fonts. Web sites do not require specifying a
particular type of font and are normally displayed with a font which is specified by the browser
settings. But those web sites that are normally specified with a specific font are displayed with
Sans Serif fonts as a general rule.

4. Font Metrics

Understanding of font metrics is of great importance when designing fonts. Characters of most
scripts of the world rest on an imagery horizontal line. This horizontal line is called a Baseline.
Some glyphs (such as English letter „y‟) of scripts have certain parts below baseline, and distance
between edge of lowest descending part of the character of a script and the baseline is known as
descent. And the part which descends below the baseline is called Descender. As opposed to the
descent, certain characters of scripts have parts spanning upwards vertically such as letter „h‟ and
the distance between the character or the glyph of a script which spans farthest upwards and the
baseline is known as ascent. Since languages such as English and German have capital and
simple letters, heights that are taken by capital letters are known as Cap Height. When glyphs are
aligned horizontally, an imaginary median line can be drawn above most of upper edge of
English simple letters and this line is known as median. The distance between median line and
baseline is called x-height. Sinhala and Tamil belong to Indic languages and they do not have
Capital and Simple letters.

5. Bitmap fonts

Bitmap fonts store their glyphs as an array of pixels or bitmaps. These fonts are also known less
commonly as Raster fonts since bitmap fonts are simply a collection of Raster images of Glyphs.
For each character of a font with single size, an image is created. For different sizes of a font,
different sets of images to suit those sizes are created. As an example, if three different sizes of
font are created with any combination of Bold and Italic sets, 12 different completely sets of
fonts have to be created. Bitmap fonts are easier to create, and faster to render, but they have
certain drawbacks. If Bitmap fonts to be arbitrarily scale up or to magnify the font to a larger
size, the visual appearance of the font may not be appealing due to jagged edges of bitmap.
Some of the advantages of Bitmap fonts are that they are extremely fast and easier to render; and
they are easier to create than the other kinds. In addition, bitmaps give the same output when
unscaled.

Page | 42

Due to speed and ease of rendering, Bitmap fonts are used for displaying on Linux and
Windows recovery consoles. Bitmaps are also used in systems which have fewer resources such
as embedded systems.

6. Outline fonts

Outline fonts are also known as Vector fonts as mentioned previously since borders and curves of
characters of an outline font are given mathematically and are rendered by either Operating System,
Software Application or printer. Outline fonts use Bezier curves in creating Vector fonts. Since curves
and lines are given in mathematical formula, outline fonts can be scaled bigger without causing pixilation.
Although outline fonts are aesthetically appealing, they require more processing and could produce
undesirable rendering depending upon the font, and the rendering software, and output size. One of the
major problems of outline fonts is the inability of accurately rendering of Bezier curves onto raster
display. This has been overcome by methods, such as Font Hinting, which require more sophisticated and
expensive software.

Historically, Adobe developed outline fonts and Type I and Type 3 were some of the original fonts which
were developed. Using Postscript, the glyphs of Type I are outline fonts with Bezier curves. Unlike Type
1 of Adobe, Type 3 used more widely of PostScript language. But Type 3 had not used Font hinting and
had issues when scaling up and down especially rendering on low resolution devices.

7. True Type fonts (TTF)

True type fonts (TTF) were developed by Apple to replace adobe‟s Type 1 font in the 1980s and belong
to the outline font category. . Unlike type 1 and Type 3 of Adobe, True type fonts have become more
popular and are widely used today. In those days, True type fonts gave font developers a greater degree of
freedom and control, allowing them to manipulate to pixel level of a True Type Font which was not
possible earlier and which may not be allowed any more in the modern day TTF fonts.

Apple licensed True Type fonts to Microsoft and Microsoft developed a Postscript like language to be
used with Laser printers which was used by Apple on their Apple laser printers. Microsoft partnered with
Monotype Corporation. This was a major company tracing its history to the latter part of the 1800s.
Monotype Corporation was in manufacturing and production of printing machinery, to introduce several
new technologies in Font hinting such anti aliasing which was later developed into full blown True Type
hinting. This enabled Microsoft and Monotype engineers to use TTF fonts in low resolution devices such
as Dot Matrix printers, a major breakthrough indeed. Microsoft began using TTF fonts on Windows 3.1
and Microsoft and Monotype Corporation developed several typefaces such as Courier new compatible
with Courier, and Time New Roman compatible with Roman. These fonts have survived on some of the
latest Microsoft Operating Systems such as Vista, Microsoft Windows 2008 and Windows 7.

In 1994, Microsoft introduced smart font technology which was known as True Type Open which was
later developed into Open Type Fonts with the merger of Adobe‟s Type 1 font outlines in 1996. Today
almost every Operating System in the world uses True Type fonts.

Page | 43

8. Open Type fonts

As mentioned previously, Open Type fonts are an extension of True Type fonts with support for
Postscript font data. Open Type fonts are also known as Smart Fonts. By 1996, Microsoft and Adobe had
already formulated required standards for Open Type fonts. In western writing, usually each character is
mapped to a shape hence a one to one map exits. Open Type fonts are important for non Western writing
which may have glyphs that are created by the conjunction of two or more atomic characters or syllables.

In order for Open Type fonts to function, operating systems, or applications must support rendering of
open type fonts and an operating system accomplishes this by having a rendering engine. Microsoft
operating systems have a rendering engine which is known as Uniscribe and Linux has several rendering
engines or shaping engines: Pango, QT etc.

Data on shapes of Glyphs and also rules as to how they will be rendered are stored in Open Type Fonts as
Open Type Layout tables. These rules are parsed by a rendering engine and according to rules, shaper
will either create a single glyph joining two or more glyphs which represent atomic syllables or will place
a glyph, which represents several atomic syllables.

When creating an Open Type font, initially a TTF is created using tools such as FontLab, Fontforge or
any other vector graphic based font creating tool (TTF creation is explained in the previous chapters).
Once the font is created according a desired shape, it has to be programmed as to how the font will be
rendered. For placing rules, different tools are used depending upon the programmer. Some use Microsoft
VOLT (Visual Open type Layout Tool) or others FontForge; and some create rules by using Text editor
which are then later compiled by using MS Volt, Fontforge or any other compilers, some of which are
command line based.

9. How to place rules in Open Type fonts

Open Type fonts retain rendering information by having Open Type tables. Some of main Open Type
tables used in Non Western Writing are substitution (GSUB) , Positioning (GPOS) and Glyph Definition
(GDEF) tables which are categorized as advanced Typographic tables. Several other tables which are
used in Open Type Fonts are listed below:

1. CMAP: character to Glyph mapping
   

2. Head: Font Header
   

3. Name: Naming table etc
   

4. Post: PostScript information etc.
   

The above mentioned advanced Typographic tables are created based upon Open Type layout common
format. This format allows storing of Open Type Layout data as Script, Language System, Features, and
Lookup. The following gives a basic description of each of the above:

Script: Scripts are defined at the top level and may contain a collection of glyphs which belong to several
languages. For instance Latin Script supports English, French, and German etc. In Open Type Fonts,
multiple scripts can be supported by a single font. Arabic Script is used to write Farsi, and Urdu. Sinhala
is defined under Sinhala Script and Language.

Page | 44

Language System: the Language system modifies the appearance and function of a particular language.
For instance Urdu and Farsi have additional glyphs more than what Arabic requires. This is because Urdu
and Farsi belong to Indo-European languages although written in Arabic which belongs to the Semitic
language group. By defining a language system as Urdu, an open type font is able to render Urdu with
those which are additional and specific for Urdu language.

Features: A language defines basic features of its typographic characteristics. Certain features are
language specific and others apply to a Language group. In the absence of Language specific features,
default features are applied.

Lookup tables: Features are implemented or stored by using Lookup tables. Two specific lookup tables
are used: GPOS (Positioning) and GSUB (Substitution). Features of Open Type fonts can be implemented
using either GPOS or GSUB lookup tables or the both. GPOS and GSUB can be applied to a group or a
class of glyphs.

Appendix I: How to determine and calculate height and width of a font

1. EM Unit measure of a Font is 16 points: 1EM = 16 points
   

2. Fontlab measures height and width UPM or Unit per EM
   

3. A glyph must be within a squire of following UPM unit for different fonts (FontLab calculations)
   

   1. PS fonts 1000
      

   2. TTF 1024
      

   3. TTF on a Microsoft platform must be 2048
      

4. Assuming 1EM square is 260 mm:
   

   •   Caps = 200 mm (not needed for Sinhala and Tamil)
     

   •   Ascender = 200 mm
     

   •   x-height = 140 mm
     

   •   Descender = -60
     

     For PS font: using 1000 UPM as measure,
     

   •   Caps 200/260 * 1000 = 769
     

   •   Ascender 200/260 * 1000 = 538
     

   •   x-height 140/260 * 1000 = 769
     

   •   Descender -60/260 * 1000 = -231

Chapter Eight
What shall I do once a font is created?
Harsha Wijayawardhana

Sri Lanka requires many Sinhala and Tamil Unicode fonts. As you have seen throughout the book, we try
to encourage you to come up with many varieties of Unicode fonts for different purposes: fonts for
publishing books, cartoons etc. Sinhala and Tamil calligraphy require Unicode fonts and this is an area
one should be addressing and through which you could gain recognition. But font designing must not be
limited to Sinhala and Tamil Unicode fonts. Many requirements are still there for different shapes of
Latin fonts as well. We can come up with a set of Latin Unicode fonts which will fit in with Sinhala and
Tamil writing. Some Latin fonts with diacritic marks are required for writing Sinhala, Pali and Sanskrit
using Roman letters.

When a font is designed, everyone asks the same question: “what shall I do with my font and how can I
protect it from others copying it and from illegal use?”

A font designer like any other artist must come up with an adequate protection from violations of your
