Ben Fortuna commented on COCOON-2352: ------------------------------------- I've just created a pull request in github to add support for surrogate pairs. https://github.com/apache/cocoon/pull/1 Summary of changes: * Added instance variable to XMLEncoder to record the first surrogate of the pair - NOTE: this means the XMLEncoder is no longer thread safe. This may have implications I'm not aware of (i.e. usage in multi-threaded way) * Added unit test to demonstrate the behaviour - NOTE: I needed to add the serializers project to the test classpath, not sure if there is a better way to do this with the ant config. I look forward to any feedback or comments. regards, ben > 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, Blocks: Serializers > 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 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
