utf2any translates a file encoded in UTF-7 or UTF-8 (Unicode) into any 7- or 8-bit text format. Currently, mapping tables are supplied for LaTeX, HTML, iso-8859-1, iso-8859-15 and rfc-1345. These tables don't provide a complete mapping, but they can easily be extended to personal needs.
utfcode translates one or more Unicode numbers into UTF-7 and/or UTF-8.
