I probably misunderstand what you're doing, but Windows filenames are 
encoded as UTF-16, not UTF-8.  I would guess that you'd want to convert 
your UTF-8 encoded filenames to UTF-16 before passing them to some 
function (although maybe it would be even nicer if that img.scan{} 
function would do the conversion itself).
