No, there is a misundestanding.  I meant `unify-8859-on-decoding'.
In general, Emacs shows most basic characters OK with unify-on-encoding
turned on and unify-on-decoding off, it's not like I need fancy
characters regularly.  However, Pango sure does a nicer job and I hope
your changes doing similar things get merged into the Emacs trunk.  That
is, if another stable version is ever released.

This doesn't seem to have any effect.  The screen flickers but displays
exactly the same fonts, no matter what I choose in the menus.  Probably
because I have customized faces, not sure.
