so this is the correct way ja, ko and zh languages should look, right? I 
didn't understand how did you take those snapshots: using the old gtk.so 
or the new one? hand-removing unwanted fonts or not?

actually, we use the directfb gdk library, not the linux-fb; sadly, 
gdk_event_send_clientmessage_toall in gdk/directfb/gdkevents-directfb.c 
is empty too :(

I'll try to do some more experiments with gtk.c to see if i can force 
GTK to override fonts settings taken by libfontconfig; from my previous 
experiments it looked like font preferences overridind worked only if 
unwanted fonts were hand-removed from the system.
