Non-ASCII character produces SyntaxError in __init__.py

Recently I try the Wikipedia Lens tutorial but during the tutorial, I got an error after running the lens:
"Traceback (most recent call last):
  File "bin/wikipedia", line 30, in <module>
    from wikipedia import WikipediaLens
  File "/home/user/wikipedia/wikipedia/__init__.py", line 41
SyntaxError: Non-ASCII character '\xc3' in file /home/user/wikipedia/wikipedia/__init__.py on line 41, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details"

The workaround is to place at the beginning of __init__.py file the line: "# -*- Mode: Python; coding: utf-8; indent-tabs-mode: nil; tab-width: 4 -*-" which is incorporated automatically in the others files when we create a unity-lens project with quickly but not in init file..

Can you correct this mistake for the init file at the creation of unity-lens project?
