This module will transliterate text in the อักษรพราหมี. It is used to transliterate สันสกฤต (sa), บาลี (pi), ปรากฤต (inc-pra), ทมิฬเก่า (oty), ตุมซุก (xtq), ปรากฤตแบบอโศก (inc-ash), and โคตาน (kho). 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.

Functions

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.
