Ok, I placed (require 'python-mode) to init.el and it seems to be activated
(autoloading didn't worked for me). But M-x shows no available completions
for py-execute-file:

Possible completions are:
py-electric-backspace                  py-electric-colon
py-electric-delete                     py-end-of-def-or-class
py-execute-buffer                      py-execute-def-or-class
py-execute-import-or-reload            py-execute-region
py-execute-string

Although C-h f py-execute-file shows it and says it is defined in python-mode.el.


Next, quick test with print u'\xA9':

1. Invoke python shell manually:

M-x py-shell
>>> print u'\xA9'
©
>>>


2. Create new buffer containing the same print command, switch it to python-mode
and use py-execute-buffer:

>>> ## working on region in file /usr/tmp/python-9773IlV.py...
©
>>>


3. Close python shell (opened at step 1) and invoke py-execute-buffer again:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character u'\xa9' in position 0: ordinal not in range(128)


Is this really a python problem?  I think there is a difference in how Emacs spawns python
process in each case.
