I actually looked at this thread (https://bugs.launchpad.net/ubuntu/+source/fontconfig/+bug/36761) because simply turning the default language sacrifices the font smoothing or font rendering.
What I did was, I created ~/.fonts.conf as mentioned above by copying 69-language-selector-ja-jp.conf. I then added DejaVu fonts into fonts.conf as the first font setting for all three sections in the file, and I also added the following code (taken from the other thread linked above): <fontconfig> <match target="font"> <test name="lang" compare="contains"> <string>ja</string> </test> <edit name="embeddedbitmap" mode="assign"> <bool>false</bool> </edit> <edit name="autohint" mode="assign"> <bool>true</bool> </edit> <edit name="antialias" mode="assign"> <bool>true</bool> </edit> <edit name="hintstyle" mode="assign"> <const>hintnone</const> </edit> </match> </fontconfig> I attached my .fonts.conf which maintains the good Latin characters as well as Japanese characters (both fonts are smoothed and anti-aliased). ** Attachment added: "fonts.txt" http://launchpadlibrarian.net/34027632/fonts.txt -- Japanese font switching issue https://bugs.launchpad.net/bugs/219931 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
