CJK and Mongolian are both top-to-bottom scripts, so there is no bidi
issue involved. You only get bidi problems if scripts on a single
line go in opposite directions. In vertical text, this can happen
with English and Chinese as well as Chinese and Arabic, and /there/'s
the problem -- English and Chinese are both LTR scripts. Unicode BIDI
does need to be extended to handle vertical directionality properly.
See the first two sections of
for a brief intro. I'll try to write up something more Unicode-oriented
No, I am not asking for vertical text controls; that's what CSS's
'block-progression' property is for.
