This issue was originally discussed in django-developers:
https://groups.google.com/forum/#!topic/django-developers/1Y9LZSAOSnE
Per [http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.4 w3c],
[http://tools.ietf.org/html/rfc2616#page-104 rfc2616] and
[http://tools.ietf.org/html/bcp47 bcp47], Language tags should be parsed
in case-insensitive, however, I noticed that Django detects HTTP Accept-
Language headers in case-sensitive manner.
For example, the following headers:
{{{
Chrome: Accept-Language: zh-TW,zh;q=0.8,en-US;q=0.6,en;q=0.4
Firefox: Accept-Language: zh-tw,zh;q=0.8,en-us;q=0.5,en;q=0.3
}}}
Django will correctly display Traditional Chinese for Chrome, but won't
for Firefox because of lower-cased TW.
The fix contains two parts:
1. Fix potential case-sensitive places in code to follow case-insensitive
(for example parse_accept_lang_header())
2. Fix [https://docs.djangoproject.com/en/dev/topics/i18n/#definitions
documentation], correct the sentence "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. Both the language and the country
parts are in lower case. ", which obviously incorrect, Chrome uses tags
like zh-TW, pt-BR.
