             Summary: DOM Serialization does not correctly validate Surrogate Pairs
                 Key: XERCESC-2120
                 URL: https://issues.apache.org/jira/browse/XERCESC-2120
             Project: Xerces-C++
          Issue Type: Bug
          Components: DOM
    Affects Versions: 3.2.0
            Reporter: Andrew Blackton
         Attachments: DOMCharacterValidationTest.cpp, DomStringValidation.patch

When attempting to write an xml document containing valid UTF-16 surrogate pairs an error occurs during validation. This causes the write to fail.

It appears as though this issue was introduced with https://issues.apache.org/jira/browse/XERCESC-1854 in the following commit http://svn.apache.org/viewvc/xerces/c/trunk/src/xercesc/dom/impl/DOMLSSerializerImpl.cpp?r1=768978&r2=1226891.

I have supplied a reproducible and a potential patch. The string validator should be responsible for determining if the codepoint is part of a surrogate pair.
