Why not do the same to the typed characters?  Current behavior is
inconsistent---some characters are decoded (into iso-8859 charsets),
some are not.

I understand you, but actually, most users do not bother.  Emacs should
work `out of the box' and display the characters.  Apparently, it can
show Cyrillic letters, but won't show them, uh?

Why doesn't Emacs try to decode characters on displaying?  This can
be done only once just to check if the decoded characters can be
shown normally, not as boxes.

I use Debian Sarge which is only 1 year old.  And Emacs doesn't work
with its standard font and Cyrillic letters as is.  (Well, I didn't
try the standard package, but CVS `emacs -Q' shows boxes.)  I had enough
persistence to find the reason (here, thank you), but most users won't.
Especially since Emacs cannot even list font families (at least I don't
know how.)
