When burning files with a filename in a non-standard charset, the burn will fail. It 'hangs', in that it will sit there with the last message being 'Starting in 1 second', but a click of the Cancel button will properly cancel it.

The main window shows:
mkisofs returned an unknown error (code 1)
Operation not permitted
Please send me an email with the last output
Starting in 1 second

The debugging window shows:
[... clipped ...]
Life Skills Project Review (1).doc)
Incorrectly encoded string (La República del Paraguay.doc) encountered.
Possibly creating an invalid Joliet extension. Aborting.
