Hmm, PID/EID 1,1 is Japanese on a Mac, so FreeType is correct in
saying that encoding = FT_ENCODING_NONE because it doesn't contain
mapping tables.

Value `0' means that FreeType can't handle it, not that it is an
unknown encoding!  You have to use other means handle the encoding,
for example, looking at the PID/EID pair directly.

Yes.  I'm quite sure that Japanese for older Macs is always encoded in
SJIS.  However, you should look up the Mac documentation to verify
this.

You can't.

The latter.
