Please read the caveats there before using those. The obsolete mappings are
totally unsupported. Use at your own risk.

A long long time ago we decided to drop support for most mappings. There are
many reasons, not least of which is that some of them are moving targets,
and we don't have resources to support them. For "Shift JIS" there are many
problems because there isn't just one "Shift JIS"; each vendor has their own
flavor. The vendors should track their own mappings to Unicode, where they
differ from JIS.
The *VENDOR* mappings on the Unicode site are supplied by various vendors,
and one of the MS mappings will get you the MS variety of Shift-JIS. Note
that these are not supplied by Unicode, Inc, but by the vendors to us, so it
may take a while to get an answer, but... If you have problems with one of
these vendor mappings on the Unicode site, you can discuss it here, or fill
out our error Reporting Form.
For Shift-JIS in particular, please do read the caveats and look through the
archives of this list. There are several known mapping anomalies.
