UnmarshalException with Null Character

I'm getting the following error when umarshaling a JAXB object that has a
String with a null character (0x0).  Is is possible to have CXF encode this,
or do I need to cleanse the response of invalid XML characters? Thanks.

Re: UnmarshalException with Null Character

No. U+0000 is not a valid XML 1.0 character, and there is no escape
mechanism allowed for in XML. The same applies to all of the C0
controls and some other obscurities. This is addressed in XML 1.1, but
no SOAP interoperability standard seems to be moving to XML 1.1.  If
you have to transmit such things, you have to use a representation
other than 'string'.
