What do you mean by "buffer reencoding"?  We decode external streams
to Mule encoding on input, and then encode them as specified on
output.  "Reencoding" (duplicate encoding or transcoding) of buffer
text occurs only if explicitly requested by a Lisp program or as a
user command.

If you mean the fact that XEmacs can't handle the buggy output of TeX
(which produces invalid UTF-8 in error messages), that's a non-standard
encoding we'd like to implement, but the bug is in TeX, not in XEmacs.
