Codec Error

UnicodeEncodeError: 'charmap' codec can't encode characters in position 5-9: character maps to <undefined>

Using encoding='utf-8' on the opens fixed it as this stackoverflow post has:

I am having this same problem, but I don't understand how to fix it. I'm trying to run generate.py, but I don't know what they mean about changing encoding to utf-8. Can I do this in the source code somewhere?
