IO Error on files with characters like (, ), or comma in the file name

[tensigh]

I'm running pyFileFixity on Windows and it fails if a file name has special characters in it. Is there a fix for this? If a file has a special character the script aborts claiming the files don't exist but the files do in fact exist.

IOError: [Errno 2] No such file or directory:('C:\directory\file that (does) exist.jpg')
