Please don't mix up the MIME "charset" parameter, which denotes
a character encoding (a mapping from an octet stream to a character
stream), and the document character set in the SGML sense, which
is a set of characters each associated with a positive integer.
A single HTML document (without the embedded components)
has a single character encoding and therefore a single MIME "charset"
parameter value when transmitted by HTTP or email. All HTML
documents have the same SGML document character set, namely
ISO 10646. (To be exact, the document character set may also
be ISO 8859-1, which is however just a subset of ISO 10646).
