This module will transliterate Sanskrit language text per WT:SA TR. It is also used to transliterate Old Hindi (inc-ohi) and Old Marathi (omr).

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:sa-translit/testcases.


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