Python Non-ASCII character '\xc3'

During a python script execution, if you get the following error:

SyntaxError: Non-ASCII character '\xc3' in file text2term_topia.py on line 21, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

Add the following statement right at the begining, before all import statements.

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

Similar approach for errors with the term '\xe2'.
