There is some error when run iis_controller.py

[ca3tie1]

 File ".\iis_controller.py", line 7
SyntaxError: Non-ASCII character '\xe2' in file .\iis_controller.py on line 8, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

so i delete the banner string and there another error when use "cmd net user"

    return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xc5 in position 13: invalid continuation byte

I tried changing the file encoding but not sure what to use.
