Dejavu Sans Mono doesn't have those characters.  In such a
case, it's very difficult to decide which is the "correct"
font.

A while ago, stephen@xemacs.org suggested to utilize
fontconfig's language repertoires.  I'm going to implement
that somehow.  When it is done, for non-CJK locale users,
Emacs can select a single-width font.

No, it won't help.
