There are two unrelated problems here. The first is that the choices
are not consistent. If you're going to use 靑 for 青 as a component then
you have to use it consistently throughout the font, which is not done
and absolutely wrong. The second problem is actually rather
interesting -- using 靑 is not wrong, it is instead dated. For example,
the influential Far East C-E dictionary, originally compiled by Liang
Shiqiu 梁實秋 (1903-1987) uses it throughout. In the more recent editions
of the dictionary that give both simplified and traditional forms, 靑
is used for traditional forms while 青 is used for simplified. [I don't
know why Unicode needed to encode both variants, but it certainly
makes this e-mail easier to write!]
Anyhow, IMHO, the point that Weizhong should be making is that using 靑
is dated and Traditional Chinese is not a static, dead language -- it
is alive and today 青 is the proper and most common variant to use in
Taiwan and Hong Kong. The implication that it has anything to do with
Japan is wrong -- Liang Shiqiu was a celebrated scholar in China long
before he fled to Taiwan during the Civil War. The same usage of 靑 is
found in the Mathews dictionary, first published in Shanghai in 1931.
When Weizhiong says "Some glyphs seem coming from the Japanese Kanjis,
or some ancient alternative forms no longer popular today," the first
suggestion is dead wrong and the second implies that 靑 hasn't been
used since ancient times, which is also wrong.
Regardless, I believe Apple can easily fix the first problem
(consistency) by reassigning the glyph variants for those code points
within Heiti TC. For example, there are three glyphs available for 請
-- see GID #s 25608, 25609, and 25610. [In the Character Viewer, go to
Glyph > Font: Heiti TC.] As for the second issue, I would like to see
Apple break this into three TC fonts: an old-school font that follows
the pre-war norms and uses 25609, a formal sort of current TC font
that uses 25610, and a completely up-to-date TC font that uses 25608.
Either of the last two would work as a system font, but I agree with
Weizhong that the last one is what people expect and want, and it's
Apple's job to know that.
