Emoji not rendered on Android 15

Michel de Boer

In Android 15, all emoji have become invisible, only national flag emoji still show. On older Android version my QML app works fine.

I download the Google Noto Color Emoji font using this:
https://doc.qt.io/qt-6/android-emojis.html

The PNG emoji are removed, except for the national flags.

I can get it to work again if I bundle the windows compatible ttf file with my app and add this in my QML:

FontLoader {
        source: "qrc:/fonts/NotoColorEmoji_WindowsCompatible.ttf"
}

It does not work if I bundle the font using C++ code like this:

QFontDatabase::addApplicationFont(QStringLiteral(":/fonts/NotoColorEmoji_WindowsCompatible.ttf"));

Looks suspicious to me that this does not work, as it works for other font files.

I do not like to bundle this large font file with my app.

Is this a bug in Qt?
Is Android 15 emoji font rendering not supported yet?

Any help would be much appreciated.
