Package: emacs-gtk Version: 1:27.1+1-3.1+b1 Severity: normal X-Debbugs-Cc: Olaf Meeuwissen <paddy-h...@member.fsf.org>
Dear Maintainer, While not really a major issue, this is something that's been bugging me for quite a while now and trying to get all applications on my "desktop" to use the same "Noto Sans Mono *" font I finally decided to chase this down. The problem is that certain Japanese characters look "weird". They are close to what they are supposed to look like but not quite. One simple and obvious example is 平. In Japanese it is supposed to look like ----- \ | / ----- | and on my x-terminal-emulator (rxvt-unicode) it does but in Emacs it displays as ----- / | \ ----- | Note how the slashes are transposed. This is just one example but there are quite a few other characters that don't quite look the way there supposed to. This issue gives Japanese text a somewhat "Chinese" look. Digging into this, and much to my surprise!, I found that Emacs actually selects a *Korean* font to display all Japanese (and Chinese too!). You can use `C-u C-x =` on the character to check the font that is used to display it. Feel free to explore the HELLO text (`C-h h`) if not using Emacs for mail to get some Japanese text in your buffer. The truly odd thing is that the Japanese characters are correctly identified as belonging to the appropriate JIS standard but displayed with a Korean font notwithstanding the fact that Japanese fonts are available (and used by my x-terminal-emulator, even with LANG=C.UTF-8). For reference, this happens when running emacs --no-init-file --no-site-file emacs --no-init-file emacs with my X session's LANG set to ja_JP.UTF-8 as well as C.UTF-8 and no Xresources applied. Using *font: Noto Sans Mono-16 doesn't change that. No matter what, Emacs insists on using -GOOG-Noto Sans CJK KR-normal-normal-normal-*-21-*-*-*-*-0-iso10646-1 apart from the font size (which defaults to 13 without the .Xresources setting; that's too small to be comfortable on my 31.5" monitor ;-). I have the following "font" packages installed: $ LANG=C apt list --installed 2>/dev/null | grep font fontconfig-config/testing,now 2.13.1-4.2 all [installed,automatic] fontconfig/testing,now 2.13.1-4.2 amd64 [installed,automatic] fonts-dejavu-core/testing,now 2.37-2 all [installed,automatic] fonts-noto-cjk/testing,now 1:20201206-cjk+repack1-1 all [installed] fonts-noto-color-emoji/testing,now 2.034-1 all [installed] fonts-noto-core/testing,now 20201225-1 all [installed] fonts-noto-mono/testing,now 20201225-1 all [installed] libfontconfig1/testing,now 2.13.1-4.2 amd64 [installed,automatic] libfontenc1/testing,now 1:1.1.4-1 amd64 [installed,automatic] libxfont2/testing,now 1:2.0.5-1 amd64 [installed,automatic] and the following Noto Sans Mono CJK fonts are available: $ fc-list | grep "Noto Sans Mono CJK" /usr/share/fonts/opentype/noto/NotoSansCJK-Bold.ttc: Noto Sans Mono CJK TC:style=Bold /usr/share/fonts/opentype/noto/NotoSansCJK-Bold.ttc: Noto Sans Mono CJK SC:style=Bold /usr/share/fonts/opentype/noto/NotoSansCJK-Bold.ttc: Noto Sans Mono CJK KR:style=Bold /usr/share/fonts/opentype/noto/NotoSansCJK-Bold.ttc: Noto Sans Mono CJK HK:style=Bold /usr/share/fonts/opentype/noto/NotoSansCJK-Bold.ttc: Noto Sans Mono CJK JP:style=Bold /usr/share/fonts/opentype/noto/NotoSansCJK-Regular.ttc: Noto Sans Mono CJK SC:style=Regular /usr/share/fonts/opentype/noto/NotoSansCJK-Regular.ttc: Noto Sans Mono CJK TC:style=Regular /usr/share/fonts/opentype/noto/NotoSansCJK-Regular.ttc: Noto Sans Mono CJK HK:style=Regular /usr/share/fonts/opentype/noto/NotoSansCJK-Regular.ttc: Noto Sans Mono CJK KR:style=Regular /usr/share/fonts/opentype/noto/NotoSansCJK-Regular.ttc: Noto Sans Mono CJK JP:style=Regular If I tell Emacs to use Noto Sans Mono CJK JP, the issue goes away but then Chinese and Korean text is also displayed using the JP variant instead of the Simplified Chinese (SC), Traditional Chinese (TC), Hong Kong Chinese (HK) or Korean (KR) one as appropriate.
