UTF-8 to ANSI hack in CAboutDialog

What was the reason for this change?

#if !wxUSE_UNICODE
...
     if (str.Find('Â') != wxNOT_FOUND)
         str.Remove(str.Find('Â'), 1);

to:

     if (str.Find('�') != wxNOT_FOUND)
         str.Remove(str.Find('�'), 1);

wxFormBuilder turns the (c) symbol into UTF-8 automatically. On wxWidgets-2.8.9 ansi, it shows as a copyright symbol with an extra trash character, which this hack fixes up for the non-unicode (ansi) case.
