Module:ml-translit

This module will transliterate Malayalam language text. It is also used to transliterate Tulu.

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:ml-translit/testcases.

FunctionsEdit
