How to run a unittest method with Unicode characters in the name in IDEA?

when run a unittest method with Unicode characters,always present the 'Provide a qualified name of a function, class or module' warning.

In fact, Unicode characters are allowed as method names in Python.

Of course there is the option of manually clicking Run and then Continue Anyway to force it to run (and it actually does run successfully), but that's too tedious, is there a better way?

Is this a bug?
