Package: release.debian.org Severity: normal Tags: buster User: release.debian.org@packages.debian.org Usertags: pu X-Debbugs-CC: debian-fonts@lists.debian.org Dear Release Team, A solution for https://bugs.debian.org/907999 was recently found and the fix has been tested and pushed onto Sid. Since this bug also affects Stable, it would be better to have it fixed through a stable-pu as well. The bug lies in a Debian-provided fontconfig file (70-fonts-noto-cjk.conf) and the old version was using the "prepend_first" attribute to adjust the font priority under Chinese-locale systems, which turns out to be buggy and made font rendering to be ignoring font fallback info in CSS files and forcefully using Noto CJK fonts under certain scenarios in web browsers like Firefox and Chromium. This proposed patch would solve this bug. Please review the fix and let me know if there's any question. The full debdiff is provided as attachment. -- Regards, Boyuan Yang
