Charset problem at filenames

[GoogleCodeExporter]

What steps will reproduce the problem?
Use mp4art to store a folder.jpg at a mp4 file

mp4art --add "D:\M4A\Duisburger Les Misérables Musical Ensemble\folder.jpg" 
"D:\M4A\Duisburger Les Misérables Musical Ensemble\01 Prolog.m4a"

or

mp4art --add "%temp%\folder.jpg" "D:\M4A\Duisburger Les Misérables Musical 
Ensemble\01 Prolog.m4a"


What is the expected output? What do you see instead?

I get the error 
ERROR: unable to open D:\M4A-optimized\Duisburger Les MisÚrables Musical 
Ensemble\folder.jpg for read: No error

If I use a folder,jpg at the temp directory I get the error
ERROR: unable to open for write: D:\M4A-optimized\Duisburger Les MisÚrables 
Musical Ensemble\01 Prolog.m4a

If I use as working directory a simple directory it works...
