You have several str() likely to work around real bugs but now they are
biting back. In your code I don;t see any use for it..

Example how str() is hiding bugs for you.

>>> str(None).encode('UTF-8')
'None'
>>> None.encode('UTF-8')

Traceback (most recent call last):
  File "<pyshell#9>", line 1, in <module>
    None.encode('UTF-8')
AttributeError: 'NoneType' object has no attribute 'encode'

Get rid of all the str() and make sure you have only unicode strings
*everywhere* and start fixing all the bugs that got hidden because of
it.

Do make sure to watch the video as it explains the pain you are having
with unicode.
