Oh, I didn't see that the issue was specific to Python2. I updated the issue's title. If I understood correctly, the issue is also specific to Windows.
Do you know if your patch changes the public API? (break the compatibility)

FYI about Python3:

It is described in the PEP 383 and it does solve a real and common issue: store a filename that cannot be decoded with the filesystem encoding. The operation is reversible. In Python 3.2, there are os.fsdecode() and os.fsencode() functions. On UNIX/BSD, os.encode(os.fsdecode(x)) is x, if x is a bytes object.
The PEP 383 introduces the surrogateescape error handler which does create surrogates on decode, and convert back surrogates to bytes on encode.

In Python3, filenames are stored as unicode. On UNIX/BSD, if a filename cannot be decode, it is encoded with surrogates. To get a full unicode support in Python3, you have to support surrogates.
