I may haven't represent my idea clearly. No one wishes that fbcon can
do as good as pango. The important thing is, question marks have no
information, but scripts which may have placement issues have as
much information as the one rendered by pango.

Umm... maybe use bitblit instead of render is better? The current
mainline kernel already has features of font replacing, utf-8 decoding,
and "wide" char identification. Plenty of utf-8 bitmap fonts disperse on
the world, they just have more than 512 glyphs so vt cannot handle them,
Trust me, It's nothing more than provide a larger storage.

Thanks for reply.
