4.1.2 Language and Encoding Preferences
---------------------------------------
HTTP allows clients to express preferences for the language and encoding
of documents which servers may honor. For each of these variables, the
value is a string; it can specify a single choice, or it can be a
comma-separated list.
Normally, this list is ordered by descending preference. However,
each element can be followed by ‘;q=PRIORITY’ to specify its preference
level, a decimal number from 0 to 1; e.g., for
‘url-mime-language-string’, ‘"de, en-gb;q=0.8, en;q=0.7"’. An element
that has no ‘;q’ specification has preference level 1.
-- User Option: url-mime-charset-string
This variable specifies a preference for character sets when
documents can be served in more than one encoding.
HTTP allows specifying a series of MIME charsets which indicate
your preferred character set encodings, e.g., Latin-9 or Big5, and
these can be weighted. The default series is generated
automatically from the associated MIME types of all defined coding
systems, sorted by the coding system priority specified in Emacs.

-- User Option: url-mime-language-string
A string specifying the preferred language when servers can serve
files in several languages. Use RFC 1766 abbreviations, e.g., ‘en’
for English, ‘de’ for German.
The string can be ‘"*"’ to get the first available language (as
opposed to the default).
