FIX. RadDock - XmlException when loading layout from stream, that RadDock created. The exception is "There is no Unicode byte order mark. Cannot switch to Unicode." 
DECLINED: the issue is in the client's code.

To reproduce:

- add a dock with some windows

- save the layout with this code: 

           var stringWriter = new StringWriter();
           radDock1.SaveToXml(stringWriter);
           savedLayoutString = stringWriter.ToString(); //with this line you can save the same stream to a file and observe that it is saved with UTF-16

- load the layout with the following code:
            using (var stream = new MemoryStream())
            {
                var streamWriter = new StreamWriter(stream);
                streamWriter.Write(savedLayoutString);
                streamWriter.Flush();
                stream.Position = 0;
                radDock1.LoadFromXml(stream);
            }

Workaround - when reading the xml, replace utf-16 with utf-8
                 streamWriter.Write(File.ReadAllText("qqq.xml").Replace("utf-16", "utf-8"));

DECLINED: the issue is in the client's code. All strings in C# are UTF-16 encoded (this is their inter internal memory representation) and therefore when saving the XML to a C# string, it gets encoded in UTF-16. However, when loading the layout, the code above is using StreamWriter to write the string to a memory stream and by default the StreamWriter is not writing in UTF-16 which will result in improperly encoded data in the memory stream. To avoid that, you need to specify the encoding when initializing the StreamWriter:

            using (var stream = new MemoryStream())
            {
                var streamWriter = new StreamWriter(stream, Encoding.Unicode);
                streamWriter.Write(layout);
                streamWriter.Flush();
                stream.Position = 0;
                radDock1.LoadFromXml(stream);
            }
