// Character Set Names
// -------------------
//
// This file provides functions for converting between character set names
// in ASCII strings and charset_t values.
//
// Several names may be recorded for each character set.  The primary 
// IANA-registered name is returned by charset_name().  charset_mime_name()
// returns the same as charset_name(), unless a different name is preferred
// for MIME purposes.  (Typically the preferred MIME name is more concise,
// while the primary name is less ambiguous.)  lookup_charset() recognises
// both of these names plus a large number of IANA-defined aliases and
// many variations in case and punctuation.
