I'm seeing a complete regression.  I rebuilt from CVS HEAD, confirmed
that your change is in fontset.el, and Emacs picks AR PL ShanHeiSun
for open single quotes.  Putting the script definitions back in fixes
the problem.  I have pasted "good" and "bad" font log blocks to the
end of this message.  Those logs are particularly for Neep Alt, but
the Misc Fixed ISO10646 fonts have the same problem.
