Subject: bug#2824: 23.0.91; font-selection weirdness with

I can't reproduce the problem with the latest code. It may
be because of the fix I installed last night. Does your
Emacs have this change?

* fontset.c (fontset_from_font): Specify only registry in a
font-spec for all characters supported by that registry.

If not yet, could you please try again with the latest code?
