Module:sa-translit

This module will transliterate Sansi̱ki̱rit language text. It is also used to transliterate Apabhramsa, Old Awadhi, Old Gujarati, Old Hindi, Old Marathi, and Pali. 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.

Functions

tr(text, lang, sc)
