Yes, that's what it looks like. $ lsb_release -c No LSB modules are available. Codename: mantic $ dpkg-query -W fonts-droid-fallback fonts-droid-fallback 1:6.0.1r16-1.1build1 $ snap run --shell firefox To run a command as administrator (user "root"), use "sudo <command>". See "man sudo_root" for details. /home/gunnar$ LC_CTYPE=ja_JP.UTF-8 fc-match sans-serif DroidSansFallbackFull.ttf: "Droid Sans Fallback" "Regular" /home/gunnar$ exit exit $ LC_CTYPE=ja_JP.UTF-8 fc-match sans-serif NotoSansCJK-Regular.ttc: "Noto Sans CJK JP" "Regular" So the font configuration of the snaps prioritizes differently compared to the font configuration of the system. Reason unclear to me ATM. I also checked in Debian testing, where Firefox is conventionally packaged. Starting FF there with the Japanese locale results in the default sans-serif font "VL Gothic". But that's what's expected from the system font configuration: $ LC_CTYPE=ja_JP.UTF-8 fc-match sans-serif VL-Gothic-Regular.ttf: "VL ゴシック" "regular" (Debian with GNOME has a lot of fonts installed.) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to language-selector in Ubuntu. https://bugs.launchpad.net/bugs/2017076 Title: default Chinese font in snap apps is ugly Status in Snappy: Fix Released Status in fontconfig package in Ubuntu: Invalid Status in language-selector package in Ubuntu: Invalid Bug description: After installs Ubuntu 23.04 with Chinese language selected, the default font is chosen to AR PL UMing CN, which is very ugly.
