Using UTL_I18N.ESCAPE_REFERENCE still results in XML Parsing Failed'

Question

Trying to create an RSS feed from a list of newly delivered library materials, and it's all working except for one record with a Turkish character in it. I am trying to convert that value into AL32UTF8 (the database is UTF8) in the XMLElement call, but I still receive errors that the parsing failed at line 24, which is just before the beginning of the loop to aggregate the xmlelements.
Any pointers to what I am doing wrong, conceptually and technically, would be gratefully received, thanks very much for any assistance and/or pointers here.

Is your database characater set AL32UTF8 or UTF8. If it's not AL32UTF8 please convert and try again... Database character set UTF8 is not a complete implementation of XML's UTF-8 encoding.
