-----------------------------------
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:
https://issues.apache.org/jira/browse/THRIFT-3403?jql=text%20~%20%22surrogate%20pairs%22
