A slight improvement. Get this:

C:\junk\console>chcp 65001
Active code page: 65001

Python 2.5.2 (r252:60911, Feb 21 2008, 13:11:45) [MSC v.1310 32 bit
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys; sys.stdout.encoding
>>> print u'\xff'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
LookupError: unknown encoding: cp65001
>>> print u'\xff'.encode('utf8')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IOError: [Errno 13] Permission denied

Adding an entry to ...\lib\encodings\aliases.py as suggested did fix
the Lookup error; it took it straight to the same IOError as above.

Next step?
