The Non-Roman Script Initiative

The NRSI is a department of  SIL International, whose task is to provide assistance, research and development for SIL International and its partners to support the use of non-Roman and complex scripts in language development.

Our vision is that language communities are effectively using their preferred writing system on computers without technical barriers.

Recent additions and updates

SIL Font Subsets Lorna Priest, 2012-05-04; 149 reads
SIL's Non-Roman Script Initiative has created very comprehensive fonts for Latin and Cyrillic character sets. These are very large fonts that cover just about every need we know about in the Latin and Cyrillic world. Now, as we move into the age of mobile phone and web usage, everyone wants fonts that are small and compact. Our fonts are over a megabyte each and that is considered way too big for mobile phone usage.
We are now considering ways to subset our fonts. Current commercial font subsetting schemes remove the smart font information from a font when it subsets a font. While this may be acceptable for majority languages, we consider this unacceptable as so many languages in the world require smart diacritic positioning above and/or below base characters.

Doulos SIL Cipher Lorna A. Priest, 2012-04-17; 147 reads
The Cipher music notation is used throughout Indonesia and China for all kinds of music. The font is not intended for general orthographic use. This solution is primarily intended for fairly straightforward songbooks for singers, not for complex instrumental music. It can handle harmony lines fine, but not a lot of intricacies or subtleties (e.g. no staccato).
The Doulos SIL Cipher font is still in development. We are looking for feedback from the Indonesian and Chinese Cipher music notation user community.

Unicode BMP Fallback Font Bob Hallissy, 2012-03-26; 30359 reads
Intended for debugging, this font contains a glyph for every character in the Basic Multilingual plane (including Private Use Area) of Unicode 6.1, each glyph consisting of a box enclosing the four hex digits identifying the Unicode scalar value.

Namdhinggo SIL Lorna Priest, 2012-02-28; 402 reads
The Namdhinggo SIL Unicode font for the Limbu script is still in development. However, we believe the font is useful in its present state and thus we are releasing it as a "Font in Development".

Encore2Unicode update for Unicode 6.1.
Encore2Unicode is a command-line utility for Windows that can examine a font built using the Encore font system and create a draft TECkit mapping table for converting data using that font to (and back from) Unicode.

The Mondulkiri fonts provide Unicode support for the Khmer script. These fonts are provided free of charge. Previous versions of the fonts have been available since 2003 but are now available for the first time on the SIL website. There are four main fonts available.

Charis SIL NRSI staff, 2011-09-13; 448996 reads
13 Sept and 25 Aug 2011 — Two recent updates! These two updates include fixing line-spacing/clipping issues and encoding official Unicode codepoints for all PUA characters which were added to Unicode 5.2 and 6.0. No new characters were added.
Charis SIL is a Unicode-encoded serif font. Besides having a comprehensive inventory of glyphs needed for almost any Roman- or Cyrillic-based writing system, it also contains the entire inventory of the International Phonetic Alphabet. It has built-in “smart-font” capabilities, so diacritics are properly placed.
Charis is similar to Bitstream Charter, one of the first fonts designed specifically for laser printers. It is highly readable and holds up well in less-than-ideal reproduction environments. It also has a full set of styles - regular, italic, bold, bold italic - and so is more useful in general publishing than Doulos SIL. Charis is a serif, proportionally-spaced font optimized for readability in long printed documents.

Doulos SIL NRSI staff, 2011-09-13; 782465 reads
13 Sept and 25 Aug 2011 — Two recent updates! These two updates include fixing line-spacing/clipping issues and encoding official Unicode codepoints for all PUA characters which were added to Unicode 5.2 and 6.0. No new characters were added.
Doulos SIL is a Unicode-encoded serif font similar to Times New Roman. Besides having a comprehensive inventory of glyphs needed for almost any Roman- or Cyrillic-based writing system, it also contains the entire inventory of the International Phonetic Alphabet. It has built-in “smart-font” capabilities, so diacritics are properly placed.
Doulos is very similar to Times/Times New Roman, but only has a single face - regular. It is intended for use alongside other Times-like fonts where a range of styles (italic, bold) are not needed.

Gentium — a typeface for the nations Victor Gaultney, 2011-09-13; 1392822 reads
13 Sept and 25 Aug 2011 — Two recent updates! These two updates include fixing line-spacing/clipping issues and encoding official Unicode codepoints for all PUA characters which were added to Unicode 5.2 and 6.0. No new characters were added.

Gentium is a typeface family designed to enable the diverse ethnic groups around the world who use the Latin script to produce readable, high-quality publications. It supports a wide range of Latin-based alphabets and includes glyphs that correspond to all the Latin ranges of Unicode.

Andika Annie Olsen, 2011-09-12; 158366 reads
2011-09-12 — New Release! There were some major line-spacing/clipping issues and we hope these are resolved in this version.
Andika is a sans serif, Unicode-compliant font designed especially for literacy use, taking into account the needs of beginning readers. The focus is on clear, easy-to-perceive letterforms that will not be readily confused with one another.

Annapurna SIL Fonts Jon Coblentz, 2011-08-02; 3997 reads
Annapurna SIL is a Unicode-based font family with support for the many diverse languages that use Devanagari script to produce readable, high-quality publications. The design is intended to be highly readable, reasonably compact, and visually attractive. These fonts are named after the majestic Annapurna mountain range of Nepal.

Using SIL Fonts on Web Pages Victor Gaultney, 2010-09-10; 5561 reads
2011-07-28 Andika and Gentium Basic are now available for use on web pages via the Google Web Fonts service, with more to follow in the future.
SIL fonts can be successfully used on web pages. There are many strategies available, and some tricks to making them work well.

Abyssinica SIL Lorna A. Priest, 2010-12-15; 82719 reads

Basic Set of characters needed in a Non-Roman font NRSI team, 2010-12-09; 3008 reads

The Digital Divide Alan Conner, 2001-01-01; 14034 reads
SIL chartered the Non-Roman Script Initiative (NRSI) to enable ethnic minorities to bridge the digital divide.

An introduction to keyboard design theory: What goes where? Martin Hosken, 2003-02-17; 63679 reads
Designing a keyboard is relatively easy: you just allocate codepoints to keystrokes. The difficulty comes when trying to decide what codepoints to assign to what keystrokes. Do you design based around the characters on the keytops of a user's keyboard or the relative position of the keys? What do you do if you want to be able to type more characters than there are keys in your keyboard?
