How do I encode UTF-8 using the XStream framework?

Question

Per XStream\'s FAQ its default parser does not preserve UTF-8 document encoding, and one must provide their own encoder. How does one do this?

Thanks!

Answer 1

Create a Writer with UTF-8 encoding. Pass the Writer as an argument to XStream's toXML method.

XStream xstream = new xStream();
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

Writer writer = new OutputStreamWriter(outputStream, "UTF-8");

xStream.toXML(object, writer);
String xml = outputStream.toString("UTF-8");

You may also use that Writer to include the XML Declaration.

writer.write("");
xStream.toXML(object, writer);
