Andreas Joseph Krogh created FOP-2884:
-----------------------------------------

             Summary: Rendering emoji doesn't work
                 Key: FOP-2884
                 URL: https://issues.apache.org/jira/browse/FOP-2884
             Project: FOP
          Issue Type: Bug
          Components: font/unqualified
    Affects Versions: 2.3
         Environment: oracle-jdk-11, ubuntu Linux
            Reporter: Andreas Joseph Krogh
         Attachments: pdf_with_smiley_test.pdf

The following code (in Scala, but it's easy enough to understand for Java-devs) \
renders the smiley-emoji  😃 as '#'-character.

      val tmpFilePath = Paths.get("/tmp/pdf_with_smiley_test.pdf")
      val out = Files.newOutputStream(tmpFilePath, \
                StandardOpenOption.TRUNCATE_EXISTING)
      val fopFactory = new FopFactoryBuilder(getClass.getResource("/").toURI).build
      val agent = fopFactory.newFOUserAgent()
      val fop: Fop = fopFactory.newFop(MimeConstants.MIME_PDF, agent, out)
      val transformer: Transformer = TransformerFactory.newInstance.newTransformer
      val res: Result = new SAXResult(fop.getDefaultHandler)
      val source = new StreamSource(new ByteArrayInputStream(xml.getBytes()))
      transformer.transform(source, res)
   }
}

{code}
The output in the PDF is "Hi # smile!" instead of "Hi 😃 smile!"
