Yesterday I compiled emacs from CVS by doing:

  cvs -z3 -d:pserver:anonymous@cvs.savannah.gnu.org:/sources/emacs co emacs
  ./configure --prefix=/opt/emacs-cvs --program-suffix=.em23 --with-x-toolkit --enable-font-backend --with-xft

It seems to work ok with one for me very important exception: glyphs in the Private Use Area are not rendered correctly. They simply appear as empty boxes in the buffers. This bug seems to have been around for quite some time (introduced somewhere between December and February, I think -- judging from the ubuntu packages maintained by Alexandre Vassalotti).

I hope this can be fixed soon, since it is crucial for my work. I use a lot of glyphs from the PUA in my research (Old Norse Philology).

Best regards

I have improved the documentation for fontsets, including adding several 
examples of the use of set-fontset-font, which seems to be the preferred 
way of specifying fonts for particular characters in Emacs 23.
