Purpose +/-

This module will transliterate text written in “Lingua Tatarica”.

The module should preferably not be called directly from templates or other modules. To use it from a template, use {{xlit}}. Within a module, use Module:languages#Language:transliterate.

For testcases, see Module:tt-translit/testcases.

Functions +/-

tr(text, lang, sc)
Transliterates a given piece of text written in the script specified by sc, and language specified by lang. When the transliteration fails, returns nil.
