This fails in Python 2
>>> str("a", encoding="utf-8")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: str() takes at most 1 argument (2 given)
...unless you have redefined str, e. g. with
>>> str = unicode
>>> str("a", encoding="utf-8")
u'a'

Don' try to decode an already decoded string; use it directly:
