Fix python error: SyntaxError: Non-ASCII character.

This can be fix easy ... just add the below line at top of the python file:

# coding: utf-8

You will see now something like this error:

SyntaxError: invalid syntax

... but also will be point to the bad encoding character with : ^
For example I had this:

usertest@home:~$ python sunet.py 
  File "sunet.py", line 22
    def  __init__ ( self , a , b , c ) :
                                 ^
SyntaxError: invalid syntax
