မေႃႇၵျူး:Brah-translit
Appearance
This module will transliterate text in the Brahmi script. It is used to transliterate Ashokan Prakrit, Kamarupi Prakrit, Khotanese, တမီးလ်ၵဝ်ႇ, ပႃႇလိ, Ardhamagadhi Prakrit, Maharastri Prakrit, သေႃရသႄၼီး ပရၵ်ႉၶရိတ်ႉ, သၢၼ်းသၶရိတ်ႉ, 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.
