[issue6450] normpath() sometimes maps unicode to str

[Erik Sandberg]

New submission from Erik Sandberg <sandberg at virtutech.com>:

On Linux, I get the following:

>>> import os
>>> os.path.normpath(u'/')
'/'

I would expect unicode to be mapped to unicode. os.path.abspath() has
the same problem, see also issue 3426.

This causes problems in my project, where a function requires its
parameters to be Unicode. Do the standard Python library functions that
operate on strings guarantee anything in general with respect to
conserving unicode? Can I make any assumption as to which codec was used
to encode the str returned from normpath?
