Yes. CP1252.TXT from the Unicode Consortium also has 0x9E as LATIN
SMALL LETTER Z WITH CARON.
Kazu> Q2) However the encoding is different from the one above. Is
Kazu> this encoding correct?
The encoding below "ESC $ - 1" uses a multibyte private charset in the
GR register, then switches back to Latin-1 with "ESC - A". Since
Windows 1252 is just Latin-1 in 0xA0--0xFF, this is the expected
result. I don't recognize the encoding offhand, but I guess it's some
transform of Unicode, probably the mule-unicode charset.

Then the obvious advice is that mew should just use that encoding, and
recommend GNU Emacs to those who insist on Windows 1252 (etc) instead
of ISO 8859/1. I doubt that XEmacs will use this private charset;
it's really too late to add to 21.4, and 21.5 will take Stefan's
advice and recommend Unicode (UTF-8) for this purpose. We recognize
the backward compatibility problem that mew faces, but prefer all
standard-with-XEmacs external encodings to be standard to improve
portability to other apps, and to leave all ISO 2022 private charsets
to the user. It's a tough choice.
The only real question is will emacs-unicode continue to support the
mule-unicode charsets as external encodings. I suppose so, but you'd
have to ask Handa-san and/or Dave Love. If not, then I suggest you
follow Stefan's advice and start moving to UTF-8 immediately.
