Description:
I installed mysql 8.0 on a fresh Win Server 2019. After installation I'm not able to open the Servers Option File (my.ini).

Error: Error opening configuration file. UnicodeDecodeError: 'charmap' codec can't be decoded byte 0x9d in position 4292: character maps to <undefined>. 

I have never touched the my.ini in any way.

How to repeat:
German Windows Server 2019. Fresh Install.

Added information: I opened the configuration file with the workbench (Version 8.0 CE)

That fixed my problem that I could not restart the service after editing the my.ini with the build-in Windows Editor (I saved the file as UNICODE, nevertheless it wasn't working after restarting, now used notepad++ and it's working fine). But I still can't access the option page in the workbench. 
Deinstalled the server, deleted all files, reinstalled mysql 8.0 -> Same error.

Hello Henning Schmidt,

Thank you for the bug report and feedback.
This might be fixed in WB 8.0.24, hence wait until 8.0.24 is out and try again. Thanks.
