Or an _ordered_list_ of those as input. See also the Languages while you
are at it;  and the Accept: type as well - they are all dimensions of the
same problem. And they are not orthogonal; i.e. there is an easy semantic
coupling between languages and charset - and the Accept list may prompt
you to send a gif or pdf in some cases.

You'd have to track which Accept, Accept-Language and Accept-Charset you
negotiated on. As applications may (also) do i18n and localizations
optimizations such as swapping ',' into '.' or abusing charsets and doing
locale specific normalizations of the unicode cast.
