The most robust way is to use unicode strings:

>>> print u"? and also \N{GREEK CAPITAL LETTER LAMDA}"
? and also ?

If you use literals like the omega above you also have to specify the
encoding of your script in the first or second line, typically

# -*- coding: utf-8 -*-

Only 8-bit encodings are allowed.
