[jira] [Commented] (XALANJ-2560) ToXMLStream does not support
unicode supplementary characters
[ https://issues.apache.org/jira/browse/XALANJ-2560?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16310888#comment-16310888 ]
Thomas Scheffler commented on XALANJ-2560:
------------------------------------------
As Xalan produces invalid XML. This is a real show stopper. Sad to see, that it is still unresolved.

> Key: XALANJ-2560
> URL: https://issues.apache.org/jira/browse/XALANJ-2560
> Project: XalanJ2
> Issue Type: Bug
> Security Level: No security risk; visible to anyone(Ordinary problems in Xalan projects. Anybody can view the issue.)
> Components: Serialization
> Affects Versions: 2.7.1
> Environment: Xalan 2.7.1 serializer.
> Tested on Ubuntu 12.04 with Oracle JDK 1.7.0_05.
> Reporter: Damien Guillaume
> Labels: serialization, unicode

> org.apache.xml.serializer.ToXMLStream (which extends ToStream) does not support serialization of unicode supplementary characters such as U+1D49C. It creates invalid characters entities like "��" instead of "𝒜" (or F0 9D 92 9C with UTF-8). ToXMLStream is used by LSSerializer when Xalan's serializer is on the classpath.
> org.apache.xml.serialize.DOMSerializerImpl (included in Xerces) does not have this problem, but it is deprecated since Xerces 2.9.0, so this is a regression.
