Ben Fortuna commented on COCOON-2352:
-------------------------------------
Hi Francesco,
The JAR I am using is: org.apache.cocoon:cocoon-serializers-charsets:1.0.2 -
which appears to be built in 2012. It looks like it came from the BRANCH_2_1.X
branch but I can't be certain..
I will try to make a patch - the easiest for me would a pull request on GitHub,
but if you prefer a patch file I can do that also.
I am looking at the unit tests in the project and it is a little difficult to
get my head around. Would you prefer that I write a unit test using htmlunit,
or junit, or no preference? It appears tests haven't been updated for a number
of years. Many thanks.

> 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
