-----------------------------------

             Summary: XMLEncoder doesn't support Unicode surrogate pairs
                 Key: COCOON-2352
                 URL: https://issues.apache.org/jira/browse/COCOON-2352
             Project: Cocoon
          Issue Type: Bug
          Components: * Cocoon Core
            Reporter: Ben Fortuna


Whilst investigating an issue with the Sling project and support for emoji characters, I've come to notice that the XMLEncoder used by HTMLSerializer doesn't support Unicode surrogate pairs to represent higher order unicode characters.

A simple unit test that demonstrates this issue is here:

https://github.com/micronode/whistlepost/blob/master/whistlepost-rewrite-lib/src/test/groovy/org/apache/cocoon/components/serializers/encoding/XMLEncoderTest.groovy

More background info here also: SLING-5973

This seems to have been identified/addressed in other Apache projects also:
