I'm -0 on allowing __fspath__ to return bytes, but we can see what others
think.
With the PEP 383, a bytes filename can be stored as str using the
surrogateescape error handler. So DirEntry can convert a bytes path to
str using os.fsdecode().
I am far from a unicode expert, but if I understand this correctly you
are proposing that DirEntry.__whatever__ can always return a str using
the surogateescape (SE) method.
However, before this SE string can be used, it would need to be
converted back to bytes, and with the same SE method, yes? And this has
already been implemented in the stdlib?
So my concern in such a case is what happens if we pass this SE string
somewhere else: a UTF-8 file, or over a socket, or into a database?
Does this have issues that we wouldn't face if we just used bytes?
