Question

我有一些代码将地图编码为XML，然后解码此XML。当地图值只有ASCII字符时，它会按预期工作，否则会崩溃。如何使其与Unicode字符一起使用？请记住，我有使用此方案编码的遗留数据，因此不能选择切换到完全不同的编码方法。

String firstName = "Влади́мир";
Map<String, Object> map = new HashMap<String, Object>();
map.put("firstName", firstName);
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
XMLEncoder encoder = new XMLEncoder(outputStream);
encoder.writeObject(map);
encoder.close();
String serialized = outputStream.toString("UTF-8");
System.out.println(serialized); // output looks OK
XMLDecoder decoder = new XMLDecoder(new StringInputStream(serialized));
Map<String, Object> mapOut = (Map<String, Object>) decoder.readObject(); // exception!

错误：

org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0x12) was 
found in the element content of the document.

Java XMLEncoder，XMLDecoder和UTF-8
