 How do I reply to your messages without Gnus splitting my replies
into
 multiple parts?   
A few months ago, (setq mm-coding-system-priorities '(iso-8859-1 utf-8)) in
your ~/.xemacs/init.el would have done it. 
Unfortunately, a bug seems to have crept in since then, and I didn’t notice
because my local installation is so hacked; the below test case now gives me
iso-8859-1 , which it shouldn’t, since neither UTF-8 \xc6\x92 (U+0192) nor
UTF-8 \xe5\x8d\x97 (U+5357) can be remapped to ISO 8859-1.
(let* ((temp-buffer (generate-new-buffer "5wDxDXtyU"))
       begin end csets psets)
  (require 'latin-unity)
  (set-buffer temp-buffer)
  (insert (decode-coding-string "
> [...] m\xc3\xb6glich  
\xc6\x92 \xe5\x8d\x97" 'utf-8))
  (setq begin (point-min)
	end (point-max)
	csets (latin-unity-representations-feasible-region begin end)
	psets (latin-unity-representations-present-region begin end))
  (latin-unity-maybe-remap begin end 'iso-8859-1 csets psets))
Stephen, have you any obvious suggestions as to where to look for the issue
here?
 It doesn't seem to like your UTF-8 encoded stuff mixed
 with my ASCII replies.  I tried setting the coding system of the reply
 buffer to UTF-8, but that mangled the parts of your message that I was
 replying to (double encoding?).  Is there some "reply to this message
 using the coding system of the original message" function? 
No; it’s not needed when the normal reply code isn’t buggy. 
 I'm coding system illiterate.  It's about time I started
learning how
 coding systems work.
