Francesco Chicchiriccò commented on COCOON-2352:
------------------------------------------------
Hi [~fortuna], thanks for your PR (which is also the very first coming from
github, wow...)!
As you can see from [1] (I had to download the PR as diff, then rework it a bit
to make it compatible with Cocoon 2.1 JUnit tests [2]), your changes are now
incorporated.
I have also added [3] to properly handle XMLEncoder#highSurrogate
re-initialization.
Shall we close this issue, then?

> 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
