encoding: make HFS+ ignore code Python 3 compatible unichr() doesn't exist in Python 3. chr() is the equivalent there. Unfortunately, we can't use chr() outright because Python 2 only accepts values smaller than 256. Also, Python 3 returns an int when accessing a character of a bytes type (s[x]). So, we have to ord() the values in the assert statement.
