I remember seeing these kind of errors when my terminal could not understand utf-8. Maybe your locale is not using UTF-8?

$ locale                                                                                                                                       13.3s  Sa 21 Mär 2020 12:36:02 CET

Thanks for the hint, I'll try to set LC_ALL to UTF-8!

no, that looks right already
