I've been trying to translate my app, from its original language, English (US) over to German (Germany) and Japanese (Japan).  I had a custom `qtquickcontrols2.conf` for Japanese that specified a larger font size for QML, which was loading correct (via the RCC's `lang="ja"` specifier in the `.qrc` file.

It worked well on Linux, macOS, and Android, but the fonts were still somewhat small when I put it on my iPad (who's original language was English (US)).

I changed the locale to Japanese on my iPad and was still seeing the smaller fonts.  Even tried restarting.

In QML, I added in this logging line:

```

print(Qt.locale().name);

```

And in xcode the log reported that the locale was `en_US`.  But my app was displaying the Japanese strings correctly (from an embedded .qm file)
