[FIXED] What is the correct LANGUAGE_CODE for the UK?

Issue

Is the correct LANGUAGE_CODE for British English 'en-GB' or 'en-gb' when using I18N?

Does it make a difference?

Solution

Per the definition of language code given in the Django Docs:

language code

Represents the name of a language. Browsers send the names of the languages they accept in the Accept-Language HTTP header using this format. Examples: it, de-at, es, pt-br. Language codes are generally represented in lowercase, but the HTTP Accept-Language header is case-insensitive. The separator is a dash.

Emphasis mine. Either capitalization is accepted, but the lowercase form is more typical.
