Cumulus is not handling internation file names correctly

When adding an object to Cumulus with a chinese file name the following error occurs:

Traceback (most recent call last):

fixed with b77f65c

John, could you please fix the unit test for this issue so that it doesn't expect the CUMULUS_WORD environment variable?
