I think I have found the problem, it seems to be a bug in the
conversion table from Big5 to Unicode (BIG5.TXT from unicode.org).



When I commented out the lines on BIG5.TXT which map charactes
to U+FFFD, 

    (split-char (string-to-char (decode-coding-string "\357\277\275" 'utf-8)))

evaluates to

    (jit-ucs-charset-0 106 50)

and XEmacs can display U+FFFD correctly in normal text files.

Web-pages containing U+FFFD are still not displayed perfectly when
viewed with w3m.el under XEmacs, but it is much better than before.
Before, everything from the first occurrence of U+FFFD to the end
of the page became garbage Chinese characters.

Now, U+FFFD is displayed as '???' (3 question marks) in a web-page and
the rest of the page remains readable.
