每XStream的的常见问题及其默认解析器不会保留UTF-8编码的文件，并且必须提供自己的编码器。 怎样才能做到这一点？
谢谢！
Answer 1:
创建UTF-8编码作家。 传作家作为参数传递给XStream的的方法toxml用于。
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");
您也可以使用该作家包括XML声明。
writer.write("<?xml version=\"1.0\" encoding=\"UTF-8\" ?>");
xStream.toXML(object, writer);
Answer 2:
另一解决方案是，以启动XStream的对象与正确的编码，通过驱动器。 使用DomDriver这将是这样的：
XStream xstream = new XStream(new DomDriver("UTF-8"));
（默认）PrettyPrintWriter将通过与正确的编码的OutputStream缠绕。 你不能添加UTF-8头这样然而...
Answer 3:
与当前版本的XStream的，@杰罗米的例子是这样的：
ByteArrayOutputStream stream = new ByteArrayOutputStream();
OutputStreamWriter writer = new OutputStreamWriter(stream, "UTF-8");
HierarchicalStreamWriter xmlWriter = new PrettyPrintWriter(writer);
xstream.marshal(object, xmlWriter);
return new String(stream.toByteArray(), "UTF-8");
