Despite working properly yesterday, suddenly all Japanese text in the bookmarks, URL, tabs, web pages are rendered in a different, difficult-to-read brush-stroke Japanese font in Chromium (version 80.0.3987.100) on Ubuntu 19.10. I attempted to fix this by setting the fonts for Japanese script in the Advanced Font settings and restarting the session, but nothing has changed. (Before changing these settings, all the Japanese font settings were set to "Use default" by the way.)
If I change the font settings to Times New Roman, Ubuntu, or any other non-Japanese font for Japanese script, the brush-stroke font is displayed. However, if I set the default font to Noto, the problem is not solved.
If I delete the brush-stroke fonts (e.g., Aoyagi Kouzan) from my Home folder and restart the session, Japanese is displayed as normal in Chromium. However, I would like to be able to use these fonts in texts occasionally.
The fact that it works in Firefox would lead one to believe that it is specific to Chromium, not Ubuntu, but at the same time, I don't have this problem in Windows, so it is possible that Chromium is using some "default" Japanese font setting from Ubuntu that I haven't been able to track down. Any ideas on how to fix this?
