This module will transliterate ภาษาอาหรับ text. It is also used to transliterate อะดีเกยา, อะวาร์, เชเชน, อิงกุช, and คาบาร์เดีย.
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:ar-translit/testcases.
Functions
tr(text, lang, sc)- Transliterates a given piece of
textwritten in the script specified by the codesc, and language specified by the codelang. - When the transliteration fails, returns
nil.
