Non-Roman UI strings are blank in Japanese locale

[tsundoku39]

When the system language is set to Japanese, most of the UI strings in Qt applications appear blank. Roman text (like keyboard shortcuts) is still displayed.

I tested the Japanese locale. Everything works perfectly. Check your system font settings. Try choose Noto Sans CJK JP fonts by default (see screenshot).

I see what you mean, but there is still a problem. Native Haiku applications are able to use fallback fonts to substitute missing glyphs, so Qt applications should be able to do this too instead of relying on one font containing everything. See:

https://git.haiku-os.org/haiku/tree/src/servers/app/font/GlyphLayoutEngine.h

Maybe add a bunch of other families to

qthaikuplugins/platforms/qhaikuplatform/haiku/qhaikuplatformfontdatabase.cpp

Line 124 in f74f391

QStringList QHaikuPlatformFontDatabase::fallbacksForFamily(const QString &family,
