Running @symac's patched version with Python 2.7.8 in PowerShell in Windows 8.1 Pro N. Issue seems to be caused by NTFS / Windows not supporting "?" in filenames.

With the proper exception handling introduced in 7dad7e6 and 3e1c728, the severity of this is mitigated since 1. CommonsDownloader will no longer crash when such a problem occurs 2/ The incident will be logged and notified to the user.
