มอดูล:Khmr-translit

This module will transliterate text in the อักษรเขมร. It is used to transliterate สันสกฤต (sa), บาลี (pi), เขมรเก่า (okz), เขมร (km), and เขมรกลาง (xhm).

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:Khmr-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.
