+First of all, those characters are UTF-8 byte order marks. It is
+mandatory for UTF-8 text stream to not be misinterpreted as other
+Under MS.NET 1.x, XmlSerializer serializes output with "Default"
+encoding when it is indicated to serialize objects into Stream.
+However, it is often problematic. Thus .NET 2.0 uses UTF8Encoding for
+Stream input.
+The code is apparently bad because it incorrectly guesses that output
+is ASCIIEncoding. It won't work on .NET 2.0.
