New submission from mike bayer <mike...@zzzcomputing.com>:
given the following Python 2 source file:
# -*- encoding: utf-8
print 'bien mangé'
It can be converted to Python 3 using 2's 2to3 tool:
classic$ 2to3 test.py
... omitted ...
--- test.py (original)
+++ test.py (refactored)
@@ -1,3 +1,3 @@
# -*- encoding: utf-8
-print 'bien mangé'

However that of Python 3.1.1 fails:
