Hi all.
I can't understand the problem with my code...
I wrote a simple test function to write an XML document and in the
resulting file I find 3 strange chars before the document starting.

=== CODE ===

using( XmlTextWriter w = new
XmlTextWriter("test2.xml",System.Text.Encoding.UTF8) )
{
   w.Namespaces = false;
   w.Indentation = 4;
   w.Formatting = Formatting.Indented;
   w.WriteStartDocument();
   w.WriteStartElement("root");
   w.WriteStartElement("item");
   w.WriteAttributeString("attr","123");
   w.WriteEndElement();
   w.WriteEndElement();
   w.WriteEndDocument();
   w.Close();
}

===

And the result I get is:

===

<?xml version="1.0" encoding="utf-8"?>
<root>
   <item attr="123" />
</root>

===

Help me please!
