This module will transliterate text in the Brahmi script. It is used to transliterate Ashokan Prakrit, Magadhi Prakrit, Khotanese, Ardhamagadhi Prakrit, Maharastri Prakrit, Sauraseni Prakrit, and Tumshuqese.

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:Brah-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.
