Not a bad idea... have os.listdir() return Unicode subclasses that work
like file handles, ie. they have an extra buffer that holds the original
bytes value received from the underlying C API.
Passing these handles to open() would then do the right thing by using
whatever os.listdir() got back from the file system to open the file,
while still providing a sane way to display the filename, e.g. using
question marks for the invalid characters.
The only problem with this approach is concatenation of such handles
to form pathnames, but then perhaps those concatenations could just
work on the bytes value as well (I don't know of any OS that uses non-
ASCII path separators).
