I have not (yet) installed mule-ucs, so I cannot try to reproduce your
problem. However, I am intrigued by it.

I am not sure the bug is in core Emacs. If you open mbox in raw mode
(I understand you mean actually `raw-text'), then multibyte character
support is switched off. In consequence, the characters in the range
0x80--0x9f are OK (otherwise they would be interpreted as parts of
multibyte character representations). There is probably something
wrong in the way they are processed later.

If it appears that is it really a GNU Emacs bug, you should report it
to bug-gnu-emacs@gnu.org (you can use for it the menu-bar: [Help]
[Send Bug Report]).

Best regards
