libdvdread cannot read directories with swedish umlaut letters
libdvdread failes to read from dirs with umlaut letters, for instance "åäö". To reproduce:
This works: "vlc.exe dvd://c:\mydvd"
This doesnt work: "vlc.exe dvd://c:\mydvdåäö"
libdvdread will fail (and libdvdnav fails to after that), and ffmpeg will take over and play the dvd without handling the dvd menus. This bug can be reproduced in todays git, and older vlc versions.
Only tested on windows.
