Minimum Criteria For Language Support (I18N)

Support in Unicode

Languages may have one or more scripts for writing purpose. At least one of the scripts should be encoded in Unicode.

Locale Definition in glibc

A completely filled locale file for the language has to be present in glibc and installed at /usr/share/i18n/locales/ .

Orthography Definition in fontconfig

An orthography file for the language has to be created for fontconfig and included in the Fedora package for fontconfig.

A Unicode Font

At least one font that covers the Unicode range for the given script (of the language) which is usable must be present.

Fonts in Fedora
The Fonts SIG takes loving care of Fedora fonts. Please join this special interest group if you are interested in creating, improving, packaging, or just suggesting a font. Any help will be appreciated.

Shaping Engine

Shaping engines (e.g. Pango, Qt, ICU etc.) should support the script grammar for the script of given language (at least Pango).

Note 1

A usable font can be regarded as the one that works with or without shaping engine to provide maximum coverage for the language's writing system. Shaping engine and font may have few bugs considered together, but most of the basic script mechanism should be supported. If there is a doubt about this criteria, final verdict about a font support may be given by the users of the language.

Input Method

There should be at least one simple method for inputting text in the given language. As SCIM is the current default input method, there should be support for the language in SCIM, preferably at least one m17n keymap and any additional processing (modules) required for the language specific features.

Entry in comps

The comps file for a given distro should have the entry for the language support which lists all the necessary packages to be included that satisfy at least Font and Input Methods requirements.

Entry in anaconda

Anaconda package need to be added new language name in lang-table file in tabbed format. Once a language name is added in lang-table file and new package is built, we can use anaconda in that language. This requires that language should have got translations added to anaconda source.

Entry in system-config-languages

User should be able to select the given language from the system-config-language utility.


Note 2

These criteria are only meant for i18n support. This does not ensures the complete translation or l10n support for a given language.


Note 3

These are only minimum criteria. Thus there may be any more number of i18n/l10n packages that can be present in the given distro. E.g. additional fonts, multiple input methods and keymaps, various dictionaries and as many language packs as possible.
