UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 54: invalid start byte

Maybe is it because my system is french ? Any idea how to solve that ?

I meet this error on windows

File "C:\Program Files\Python37\lib\site-packages\aubio\__init__.py", line 26, in <module>
    from ._aubio import __version__ as version
UnicodeDecodeError: 'utf-8' codec can't decode bytes in position 945-946: invalid continuation byte

Has anyone found a way to resolve this? My system is in French too and I'm encountering the same issue.
