I didn't know that, you actually made me look it up in the Python 3
FAQ. And yes, the difference is that decode will return bytes type
instead of a string. This may or may not be a problem (bytes type is
supposed to be immutable, so it can be used in many places where a
string is used now, ex. as a dict key).
