Do not use uppercase for Japanese typography jargon, choose either of
initial capital and (perhaps italic) lowercase. Especially do not
hardcode the case, but use markup and CSS.
Rumour has it that there is (or was before DTP) a special metric unit
in Japanese typography, the kyu or q of 0.25 mm exactly. Is this
true? If so, is it still in use (and is the conventional 9pt an
approximation of 13q)? If so, it should be mentioned, but should it
be added to CSS?
It would be nice if the terminology was compatible with <http://
www.w3.org/mid/[hidden email]> (or whatever resulted
from it) and vice versa.
