Re: Mac OSX + 17,500 Kanji

I just did some rough countings and found out that any typical Unix Japanese
eucJP locale will support about 12,500 Kanjis from JIS X 0208 and JIS X 0212
not counting symbols , UDCs, and so on but counting only pre-defined
Kanji characters in the national stds.

In Solaris 8, pretty much all Unicode/UTF-8 locales whether that is
ja_JP.UTF-8, zh_CN.UTF-8, en_US.UTF-8, th_TH.UTF-8, and so on, supports about,
more or less, 20,000 ideographs from CJK Unified Ideographs Extension A,
CJK Unified Ideographs, and CJK Compatibility Ideographs in Unicode 3.0
and, among the locales, zh_CN.UTF-8 supports the biggest number of the
ideographs at about 21,205.

I'm sure other vendors are probably also doing pretty much same in
terms of the number of supported ideograph glyphs.

With regards,


PS. I had a brief chance to look at their Aqua GUI during the MacOS X
installation (in Japanese) and it sure looked wonderful and even pleasing to
eyes by the way I have to say.
