[PyQt] QActions and Unicode glyphs

[malonn]

I'm trying to add Unicode glyphs to a QAction. But, my attempts thus far are crashing my desktop (actually logging me out). How do I use Unicode characters in QActions?
I've tried directly in the IDE like so:
QAction("• my string")

I've tried via Python (3.10.5) escape sequences, like so:
QAction("\u0394 my string")

and finally, I've tried with QObject.tr(), like so:

str = QObject.tr("\u0394 my string")
QAction(str)

How do I pass unicode characters to a QAction? I don't want crashes, now-what-i-mean.
