This module will transliterate හින්දි භාෂාව text. It is also used to transliterate Angika, Awadhi, Bagheli, Mahasu Pahari, Haryanvi, Bhadrawahi, Bundeli, Palya Bareli, Braj, Chambeali, Churahi, Dhundhari, Dogri, Gaddi, Garhwali, Chhattisgarhi, Hadothi, Jaunsari, Bilaspuri, Kullu Pahari, Kurukh, Mandeali, Mewari, Malvi, Marwari, Nimadi, Pangwali, Sadri, Saraiki, Mundari, Mewati, සහ Kangri. 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:hi-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.

-- Transliteration for Hindi (possibly other languages using Devanagari script, except for Sanskrit)
