Stephen, if that is so, you should forward them to me. (If
XEmacs/Mule causes the problems, too -- I could then put a note into the
manual -- I already have some...all have been mentioned on xemacs-beta.)

X-Symbol decodes \alpha to a character of a new charset in the buffer
and encodes it when saving. Uwe, if the encoding does not work for you
(of course, X-Symbol must have been enabled in that buffer), you should
send a bug report as described in the manual.

Well, the mechanism would have just told you that you are trying to save
the private characters (please note that only the head revision of Emacs
uses the correct sequence format-annotate/encode -- choose-save-encoding).

Well, it might be similar, but not very, and it would not prevent the ~
for the character `alpha'.
 v4.4.4 will handle the situtation where different buffer would have
different `buffer-file-coding-system's. It will also rename all local
variables named `values' which is necessary in XEmacs (but nowhere
mentioned -- and extremely annoying...)

* with latin-unity: XEmacs would still store a latin-9 encoded file,
latin-unity would remap a latin-2 zcaron to a latin-9 zcaron, i.e.,
store a byte with value 184 and XEmacs would fail to store a zacute
(with a single byte)
