Subject: 23.1.96; Fail to render some Japanese characters on Windows
Date: Sat, 24 Apr 2010 08:17:41 -0700

Some Japanese characters don't render correctly.  One such example
character is the middle letter in the word game "ゲーム".  Another one
I found is the dot character here between 1 and 2 "１・２".

It is tested on GNU Emacs 23.1.96.1 (i386-mingw-nt6.1.7600) running on
Windows 7 Professional 64-bit (6.1, Build 7600).  This problem is not
new and has been observed for some time.

----------------------------------------------------------------
This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs <at> gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':



If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.

What about C-u C-x = on some Japanese characters that do display?

The above tells me that whatever font is being selected for Japanese
characters is missing those two characters. Seems unlikely, and it
almost certainly isn't the case for all Japanese fonts installed on
the Japanese version of Windows 7.

Isn't BatangChe a Korean font?  Why do your Japanese fonts get overlooked?

What do the following say (copy to the *scratch* buffer and press Ctrl-J
after each line):

(list-fonts (font-spec :registry "JISX0208*"))
(list-fonts (font-spec :registry "GB2312.1980-0"))
(list-fonts (font-spec :registry "KSC5601.1987*"))
(list-fonts (font-spec :registry "iso10646-1" :script 'kana))

Here is the result.  If you need full length lists without truncation
let me know how to avoid the truncation in the *scratch* buffer.
