This module will transliterate text in the Old Italic script. It is used to transliterate Etruscan, North Picene, Oscan, South Picene, Camunic, Faliscan, Lemnian, Lepontic, Raetic, Umbrian, and Venetic. 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:Ital-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.
