Your examples (snipped) pretty well convince me that there is a use case
for raising exceptions. We should move beyond arguing over which one
way is right. I think there should be a second argument
'ignorebad=False' to ignore undecodable files rather than raise the
exception (or 'strict=True' to stop and raise exception on non-decodable
names -- then code is 'if strict: raise ...'). I believe other
functions have a similar parameter.
