Accept Language list

Question

I would like to react to the Accept_Language that a browser sends to a website.

Does anybody know where I can get a reliable list of all available Accept_Languages that the browser might send to a website?

Thank you very much!

Answer 1

IANA Language Subtag Registry page

This is the official location where you will find all subtags available for use in language tags.

W3 said it's the authoritative list. Plus, at the link below, there is a lot more information to be had, including descriptions and other ways of understanding the ways people label themselves.

Answer 2

The IANA Language Subtag Registry page is surely the correct answer, but the list is a bit hard to parse.

I found this github repository that has a few scripts to parse it, and a set of ready-to-use JSON objects you can use in your projects:

It looks like the author is updating the repo every time the IANA list gets changed.
