How do I use non-ASCII strings in my Python script?
Python cannot tell out of the box which character set your script uses, so you have to tell it.
The error you get is
SyntaxError: Non-ASCII character '\xe2' in file bla.py on line 1, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details
Like the link in the error message tells you, PEP-0263 defines the following syntax:
# coding: utf-8
In Python 2, you still have to use
u'...' strings to properly mark a string as Unicode.
The following questions generally talk about Unicode and UTF-8, but the same mechanism applies to any encoding other than ASCII, which is unambiguous and universal.
