             Summary: HTMLSerializer not handling some unicode characters (emoji, etc.)
                 Key: SLING-5973
                 URL: https://issues.apache.org/jira/browse/SLING-5973
             Project: Sling
          Issue Type: Bug
            Reporter: Ben Fortuna


I've noticed that when I have unicode special characters (e.g. emoji) in my sling content and the sling rewriter is enabled the characters are not output correctly to the browser. For example:

😁 becomes ��

If I disable the rewriter pipeline the output is as expected.

I've looked in the code and I suspect the issue is in the HTMLSerializer from the Cocoon library, however I'm not sure why as it should be using the default encoding for output (which is UTF-8). My rewriter pipeline is using the default html-generator and html-serializer provided by sling.

My code is available on GitHub here:

It provides a very simple app/content project pair with some emoji characters in the content (see src/main/resources/SLING-INF/content/phrases.json). Many thanks.
