http://bugs.winehq.org/show_bug.cgi?id=9767

Summary: Some unicode characters show up as '?' in file selection
                    dialog
           Product: Wine
           Version: CVS/GIT
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: wine-misc
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

To reproduce, create a file with greek characters such as "ΑΒΓΔ.txt".
Run notepad and open the file in the open file dialog.
Observe that the filename shows up as "ΑΒ??.txt" instead of "ΑΒΓΔ.txt".

Lei pointed out that most fonts should have the glyphs needed to display greek
characters, so this is unlikely a font issue....
