I have a program with an "About" dialog that contains a copyright notice.
The dialog contains a couple of labels, one of which includes a copyright
symbol, expressed as "\u00a9".
When I run this on Linux/GTK or Win32 or Solaris 5.9 Motif, it works OK, but
on HP-UX11.0 and Solaris 5.8 (both Motif), the label containing the copyright
symbol does not appear at all (i.e. it's not just the symbol that is missing,
or drawn incorrectly). The following example demonstrates this; the dialog
shown has two labels, but only the second appears on the problematic
platforms.
A Swing program that contains a copyright symbol works OK, so I don't think
there's a fundamental problem with Motif. Any ideas what might be wrong?
