Turnign greek-iso filenames => utf-8 iso

=====================

i tried to insert
print( filename )
sys.exit(0)

just before the execute
and the output is just Pacman.exe as seen in 

http://superhost.gr/?page=files.py

Seens the encoding precedure successfully turned all the filenames from 
greek-iso to utf-8 without failing, why woul it still be encoding issues 
when it comes to execute?
