Actually, I know relationship between unicode and str objects very
well. That's why I only quoted the unicode-related part of
file.encoding's documentation in my original post. Thank you.

In my original post, I have figured out that sys.stdout IS a file, by
using type() function. And isinstance() function tells the same:
Python 2.5.2 (r252:60911, Dec 18 2008, 12:39:19)
[GCC 4.2.1 (Apple Inc. build 5564)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> type(sys.stdout) is file
True
>>> isinstance(sys.stdout, file)
True
So, sys.stdout SHOULD do what the doc says, otherwise there is a bug
either in implementation of sys.stdout, or in the documentation of
file.
