Right, I mentioned in some of the previous messages that I'm not
proposing this for HEAD.

Yes, I have Cyrillic characters in misc-fixed and don't have them in
adobe-courier.

I went to install all the fonts I could find in my Debian Sarge.  And
found cronyx-courier font, which looks nice _and_ has Cyrillic
characters.  However, when I customize the default face in Emacs and
set that font family, latin characters are still displayed in
adobe-courier (though Cyrillic ones are shown in cronyx-courier)...
And the customization doesn't take any effect after I restart Emacs...
Any ideas?
