Special Character Bugs?

I have some special-character behavior
that I don't think I can do anything about,
but I wanted some feedback to make sure.
Here is a sample of the DocBook XML:

<article>...
  <sect1>
    <title>G<symbol role="unicodefont">&#x266D;</symbol> Major Key
Signature</title>
    <para>The G<symbol role="unicodefont">&#x266D;</symbol> Major key
signature is</para>
  </sect1>
...</article>

The section title and para text are fine when
I run this through fop and into PDF; however,
the table of contents looses the special characters
and replaces them with a "#" sign.  This is
also a problem for <titleabbrev> which is placed
in the header of the PDF pages.

Can I control the passage of special characters
to the table of contents or page headers in
an <article>?
