Fascinating.  I just found something else out.  When I save the file,
and then reload it, the character that was successfully displayed
earlier is now displayed as an empty box.  Maybe there is only one 你
character, and sometimes Emacs can show it, and sometimes it can't.

Furthermore, when I use Options->Mule->List Character Sets, some of
the supported character sets are entirely empty boxes.  The strange
thing about that is there are definitely some characters that it shows
fine, with none of these issues.  It's pretty strange that for some
characters, it can show the Chinese characters, and for others it
can't.

My guess is there's some basic option or package that I'm missing that
will make the problem go away.  Can you (or anyone else) copy and
paste that character into an Emacs buffer?  If it works, can you think
of anything in your setup that I might not have done?  I'll take a
look myself in the meantime.

Thanks for the help.
