    Bug 617583 - Dead accents keys don't work in GTK+ applications on OSX
    
    Handle dead keys in special_ucs_table and have them converted by
    UCKeyTranslate(), so all dead key combinations can be entered.
    Later, this should be handled in the input method, just as it's
    done for X11/Win32.
