Concerning breaking existing stuff, yes, it does.

Simple unicode font (i.e. just go beyond the arbitrary historical-vga
512 glyphs limit for fbcon) might go in.  Double-width is questionable,
but it can probably simple enough to be able to get in (there is already
some code for it anyway).

But complete unicode support (with arabic ligatures, tibetan
combinations, etc.) won't ever be accepted in the kernel as that's far
too involved in terms of font rendering.  So the userland way needs to
be fixed for these anyway, and then things like chinese will go along...
