It's clear that I was wrong when I said that this doesn't seem to have 
anything to do with emacs.  The problem might be that the Cygwin-w32 
build of emacs is a relatively recent invention and may still need some 
tweaking to get all the GUI features working properly.  If you or 
someone else is motivated enough, I'm sure it would be possible to 
figure out how the Windows build finds a glyph for characters that don't 
have one in the chosen font, and to port that to the Cygwin-w32 build. 
I'm copying Daniel Colascione, the author of that build, to see if he 
has any comments.  Dan, the thread starts here:
