Subject: [project @ 2005-04-16 05:09:32 by jmb] Split out UTF-8 handling
 functions. Submit URL-encoded forms in sensible encoding:   * First entry in
 accept-charset list, if present   * Document encoding, otherwise   We may
 want to explicitly look for UTF-8, to save converting. Convert
 cnv_str_local_enc/cnv_local_enc_str to use iconv (they're now veneers for
 utf8_[to/from]_enc). Provide mechanism for looking up local system charset
 (derived from system alphabet, under RISC OS)
