Invalid XML character (Unicode: 0xdf00) error in IDT

BOE 4.1 sp2

Information Design Tool 4.1

Build: 14.1.2.1121

Version: 4.1 Support Pack 2

Datasource:   Oracle 11i

I have an ODBC connection (both 32 and 64bit) defined to a Lawson accounting system database. 

In Information Design tool, I can bring in several of the tables, but there is one particular table ( POVAGRMTLN) that as soon as I add it, I can no longer save the universe.  I get the following error.

Failed to execute runnable (java.lang.RuntimeException: An invalid XML characer (Unicode: 0xdf00_ was found in the element content: )

This happens on both Single Source and MultiSource Universes.

I can repeat the steps in Universe Design tool and can add that table, save the universe, publish it, and write a Webi off it. 

Any ideas? 

Thanks in advance,

Susan
