Summary: os.path.abspath() / os.chdir() buggy with unicode paths

Initial Comment:
Hi,

Under Windows Explorer, one can create directory names
using characters not belonging to the user locale. For
example, one of our users created a directory named
"C:\Mes Documents\コピー ～ solipsis_svn". 

Unfortunately, when trying to manipulate such a
pathname, os.path.abspath() and os.chdir() don't work
hand in hand. os.path.abspath() uses the garbled
directory name as displayed by the command prompt and
then os.chdir() refuses the path:

C:\>cd "C:\Mes Documents\??? ~ solipsis_svn"

C:\Mes Documents\??? ~ solipsis_svn>python
Python 2.4.1 (#65, Mar 30 2005, 09:13:57) [MSC v.1310
32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for
more information.
>>>
>>> import os
>>> os.curdir
'.'
>>> os.path.abspath(os.curdir)
'C:\Mes Documents\??? ~ solipsis_svn'
>>> os.chdir(os.path.abspath(os.curdir))
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
OSError: [Errno 22] Invalid argument: 'C:\Mes
Documents\??? ~ solipsis_svn'
>>>

Gasp. Sourceforge escapes HTML entities instead of showing
the real characters... These are Japanese characters, btw.
It's easy to copy/paste some Japanese characters from a Web
site and paste them into Windows Explorer to create a
directory (at least it works with Mozilla Firefox).
