Does your default font provides those glyphs? if not, then Qt will try to find a font that can and matches the original font in certain attributes (for instance, proportional font, or serifed font). The quality of the glyphs in the font Qt choses for you might then not be what you expect.

It’s best to explicitly select the fonts you want for the different languages. That’s why there’s QFont::setFamilies which takes a list:

https://doc.qt.io/qt-6/qfont.html#setFamilies
