Yes, your console window actually uses cp437, cp850 happens to map to the 
same character, and cp1252 does not.  cp1252 is the default Windows encoding 
(what Notepad uses, for example):

Python 2.6.4 (r264:75708, Oct 26 2009, 08:23:19) [MSC v.1500 32 bit (Intel)]

win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import locale
>>> locale.getdefaultlocale()
('en_US', 'cp1252')
>>> import sys
>>> sys.stdout.encoding
'cp437'
>>> print u'\xed'.encode('cp437')
í
>>> print u'\xed'.encode('cp1252')
φ
