diff_checker.py: Decode tokenizer strings using 'utf-8' encoding on Python 2

Apparently the tokenizer on Python3 has an internal mechanism to detect the right encoding and returns unicode objects.[1] But the tokenizer on Python 2 returns byte-strings which need to be explicitly decoded, otherwise the default encoding (sometimes 'ascii') is used that causes UnicodeDecodeError.

[1] See: https://docs.python.org/3/library/tokenize.html#tokenize.detect_encoding
