This patch cannot go into GTK+-1.2 because a number of 
applications depend on the fact gdk_draw_text() (etc.) 
treat there input as 16 bit strings when drawing 
16 bit fonts.

GTK+ 1.4 will have a complete revision of text handling
(see - 
probably this library is going to be renamed from "GScript" to 
"PanGo"). The demo app for this already handles 
subset 10646 fonts, font switching, accent composition,

That is closer to being acceptable, but I believe the correct
solution is simply to specify the encoding for the fonts
that GTK+ loads by default; having it as a wildcard really
never made sense (I can conceive of people using this to
get their native character set by arranging their font path,
but that was 

Some theme files may also need fixing in a similar fashion.
