Incubator:List of Wikimedia language codes

Shortcut:
I:LWLC

This page is a list of languages codes as they are used on Wikimedia sites, especially for which there are existing issues or problems.

Language codes on Wikimedia should follow the ISO 639 standard as closely as possible, but historically exceptions have been made, and sometimes an exception is still made:

A language written in more than one script:
- should have one wiki with a conversion script
- if that is not possible, name wikis with "xx[x]-xxxx" (ISO 639 language code + ISO 15924 script code), no current examples (pa - pnb?)
A language written in more than one orthography or standard should either:
- find a way to co-exist on one wiki
- name wikis with "xx[x]-x[...]" (ISO 639 language code + IETF tag), e.g. "be-tarask" or "qu-kichwa"
- old form: "nds"/"nds-nl".
For the rest, only one exception should be possible: "simple".
