My app shall display german umlaut characters like ÖÄÜöäü but all I see on the device are rectangles. I tried with different fonts. Devices I used: HTC sensation Android 4.0.3, Asus Transformer Pad Android 4.1.1 Reproducible: Always
This is probably a duplicate of this one: https://bugs.kde.org/show_bug.cgi?id=309680
What You can do is: Enumerate all available fonts on the platform with QFontDatabase::families. Some of them seem to be complete (at least with german umlauts). It is not a fix, but maybe a workaround.
Android support is now in std. Qt
