Right Arrow In GuiMenu Disappears XSL 1.72

I had a document that stopped producing PDF using FOP 0.20.5 on 
Fedora Core 5, yesterday.  I switched from fop 0.20.5 and 
docbook-xsl-1.69.1-5 to fop 0.93 and docbook-xsl-1.72.  I can now 
produce PDF output.  I'm using xsltproc from libxml2-2.6.23-1.2.  I 
had to remove the --stringparam fop.extentions 1, or fop 0.93 blows 
up.  Unfortunately, my right arrow seems to have disappeared in the 
process.

My html output still looks OK.

I am still using docbook 4.4.

My input hasn't changed and looks like:
<menuchoice>
<guimenu>Files</guimenu>
<guimenuitem>Exit</guimenuitem>
</menuchoice>

It now produces "Files # Exit", instead of the right arrow where the # is.

Any ideas?
