> When trying to serialize XML with char consisting of unicode surogate char "\uD840\uDC0B" I have tried several and non worked. XML Transformer creates XML string with escaped surogate pair separately, which makes XML unparseable. eg.: SAXParseException; Character reference "�" is an invalid XML character.
