Actually, if  a char  cannot be displayed,  it is  replaced by a  hollow box
rather than a question mark (and it only affects the display, not the actual
content of the buffer/file).  The question mark is introduced if Emacs can't
map the external char into any internal char (i.e. there is indeed a loss of
information).

Note  that Mule-UCS  is  not  part of  Emacs,  so you  want  to contact  its
author directly.  But  I don't think you're doing  anything wrong, it's just
a  limitation of  Mule-UCS, which  (I believe)  comes from  a  limitation of
Emacs-20's Mule.  I believe that  Emacs-21 will lift this limitation so that
it will be possible  to ensure that no information is lost  even in the case
where Emacs encounters an unknown char.
