မေႃႇၵျူး:Ahom-translit

This module will transliterate text in the Ahom script. It is used to transliterate ဢႃႇႁူမ်ႇ.

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:Ahom-translit/testcases.
