Bug#898022: diffoscope: Traceback when comparing paths with invalid unicode characters

Ahh! Nice spot.

Whilst this works, would it not be better if we could use bytes for
filenames throughout? I mean, AIUI there is no assumption that
filesystems need to have any form of valid encoding whatsoever, let
alone UTF-8.

However, somewhat happy to see this in diffoscope as it certainly
improves the current state of affairs. If you do commit it, please
include my testcase (or something based on it) that I added in:
