Are you just relying on the file name to detemine whether or not it's
an executable file?  That's unreliable.

Your problem could be in several places.  Character sets are often a
nightmare, and sometimes the system itself doesn't do what you expect.

Can you confirm the same behaviour with a RAR file if it has no
special characters in the name?
