Modul ini akan mentransliterasi Bahasa Gujarati teks. Ia juga digunakan untuk mentransliterasi Kachchi and Vaghri. 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:gu-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.
