Qt for Python (PySide/Shiboken)

So now I am a bit stuck: I know since Qt 5 (and Python 3) everything is Unicode, but how are Unicode code points represented in .ui Files from QT Designer a.k.a. pyside6-designer? I load such file with QUiLoader.load(): <widget class="QLabel" name="label_9"> <property name="text"> <string>🏡 whatever</string> It also does work with HTML entities like &pound; but others like &#x1F3E1; only show the box.
