I just upgrade to Calibre 0.9.3 and I can't export my books to my Kobo anymore.

These are the error messages I get:

Failed to parse 'The Black Hole War' by 'Leonard Susskind' with error: 'character mapping must return integer, None or unicode' (file: calibre_plugins.kobotouch_extended.container, line: 74)

Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 85, in run
File "site-packages\calibre\gui2\device.py", line 551, in _upload_books

InvalidEPub: Failed to parse 'The Black Hole War' by 'Leonard Susskind' with error: 'character mapping must return integer, None or unicode' (file: calibre_plugins.kobotouch_extended.container, line: 74)

------
I may have to downgrade back to Calibre 0.9.2.

Update: The Kobo Touch Extender plugin works with Calibre 0.9.2. but not with 0.9.3.
