Running "tox -e check" resulted in an uncaught exception of type UnicodeDecodeError raised by code in main within "scripts/check_sources.py" due to a failure in decoding the contents of one of the files in my ".venv" directory. The code catches exceptions due to the file being missing, but not improperly encoded. Dealing with the two types of exception in the same way would be my preferred solution. A different issue is why the files in ".venv" were being checked in the first place?
