Improving on Sam Ruby's example, to show that, in Python 3.0, code (names) can use unicode characters (also, the default encoding of the interpreter now is utf-8):
Python 3.0a3+ (py3k:61959, Mar 26 2008, 21:02:26)
[GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu6)] on linux2
Type "help", "copyright", "credits" or "license" for more
information.
>>> Iñtërnâtiônàlizætiøn = 'Iñtërnâtiônàlizætiøn'
>>> print(len(Iñtërnâtiônàlizætiøn))
20
>>>
$ python3.0
Use with care :)
