I can't reproduce this problem in idle.  Here's how the error seems to
be caused:

>>> str('abc', 'utf-8')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: decoding Unicode is not supported

Also:

>>> str(str('abc', 'utf-8'))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: decoding Unicode is not supported

This hack might work to get you farther:

    s = str(s.encode('utf-8'), IOBinding.encoding)

(ie, add the encode() part)  I don't know what should be done to
really fix it though.
