[docbook-apps] nbsp symbols in XHTML output

[Lillian Sullam]

I am writing documentation using object oriented tags for lists of classes
and methods.  In the XHTML output in Internet Explorer, all of the areas
where there are   or   in the XSLT appear as the following symbol,
 .  This does not happen in Firefox.  Is this a common problem?  Is there
an easy solution to remove the symbols?  I am using DocBook 5.0, Saxon, XEP.
Any advice would be greatly appreciated!
