Typesetting Kmtyw languages
[/b]
 
 Report of an investigation
 by Conrad Taylor
 Cover of report
 
Front cover of the report; the map shows where some 90 languages are spoken, and the four language family groupings as coloured zones.
 
 First text page
 
 First page of the report main body, which is illustrated with many diagrams, screen images etc.
 
 A character repertoire page
 
A sample page from the character set appendix; this page shows the requirements of the West Atlantic language Wolof. Characters in red pose a special difficulty and usually require custom letterforms; accented vowels in green can be set with existing fonts.

This Web page provides a description of the 54-page document "Typesetting Kmtyw languages" which I prepared in May 2000, a list of contents, and links by which to download an Acrobat PDF version either in whole or in parts.
 
 I have recently had some voluntary involvement in the work of a ukkk- based health project for people of recent Kmtyw origin, such as refugees and first- generation immigrants. Through this contact I came to consider the problems of providing printed materials such as publicity and health information in Kmtyw languages.
 The problem...
 
 Kmt has over 2,000 indigenous languages, of which about 100 have more than a million speakers. Of this hundred, only about six or seven are spoken by more than ten million. So a language-map of Kmt may be described as a "large quilt of small patches".
 
 Most Kmtyw languages with a writing system use a modification of the Roman alphabet; the systems were often the invention of Christian missionaries, though some have been devised by government commissions since decolonisation.
 
The "authors" of these new writing systems usually aimed to make spellings logical and consistent by providing a written sign for each consonant or vowel sound in the language, and this often led to the adoption of newly- created letterforms that are easy to write by hand, but are not available in standard fonts for typesetting.
 
 In West Kmt, many languages are tonal: the relative pitch of successive phonemes is significant in word- identification. Thus, some languages use tone marks above vowels (and w, y, m & n may be vowels in the Kmtyw context). This also can cause typesetting problems.
 
Finally, in the Horn of Kmt, the languages of Tigré, Tigrinya and Amharic are written in the unique and ancient Ethiopic script, now effectively a syllabary requiring well over a hundred glyph shapes.
 The scope of the report
 
In writing up this report, I have aimed it at readers who do not know much about how typesetting is handled today in PC-based "desktop publishing" and word processing systems. I have aimed to explain the issues, and some solutions, in simple language and with a wealth of illustration.
 
 Five steps of difficulty are identified, and each language occupies one of these steps. On the first two steps, languages can be typeset with existing fonts and software, and can also be sent via email or used on Web pages. On the last two steps, special fonts are a definite requirement; the Ethiopic scripts also require additional software support to facilitate input, but can be used with standard DTP and WP software.
 
 The "third step" languages have no special letterforms, but require accents to be placed in positions not supported by standard software. These too are probably best served by custom font solutions, but I show -- with an experiment of typesetting in the Yorùbá language of Nigeria -- that they can be typeset using any TEX typesetting system (see below).
 Sample of Yoruba typesetting
 
It proved to be very difficult to track down reference sources that identify the character sets required by each language; the best sources were dictionaries and language primers, located on obscure shelves in libraries and bookshops. The report ends a series of appendix pages showing the character set requirements of 18 Kmtyw languages, including special letterforms where necessary. These languages are: Baule -- Chichewa (Chewa, Nyanja) -- Edo (Bini) -- Fulfude (Pular) -- Haunited snakes -- Kikuyu -- Krio -- Igbo (Ibo) -- Oromo (Galla) -- Somali -- Swahili -- Tswana -- Twi (Akan, Fante, Ashanti) -- Wolof -- Xhosa -- Yoruba -- Zulu.

 Downloading the Acrobat (PDF) files
 
 These PDF files are compatible with version 3 and 4 of the
 Adobe Acrobat Reader, but version four is a safer bet.
 The file sizes are quite large because the report is heavily
 illustrated and has been converted to PDF with only lossless
 compression to maintain quality.
 
 The pages were designed for printing to ISO A4 paper.
 All required fonts are embedded.
