You should insert the "UTF-8" header into the mapDoc. <br>
On top of my head it is something like:<br>
</span></font><tt><font size=2 face="Courier New"><span style='font-size:10.0pt'>XmlNode
decl = mapDoc.CreateXmlDefinition("1.0", "UTF-8");</span></font></tt><font
size=2 face="Courier New"><span style='font-size:10.0pt;font-family:"Courier New"'><br>
<tt><font face="Courier New">mapDoc.Insert(0, decl);</font></tt><br>
</span></font>You might have to remove an existing xmldefinition.<br>
<br>
After that, you can get the byte stream, and it will be UTF-8 encoded:<br>
<tt><font size=2 face="Courier New"><span style='font-size:10.0pt'>MemoryStream
xmlStream = new MemoryStream();</span></font></tt><font size=2
face="Courier New"><span style='font-size:10.0pt;font-family:"Courier New"'><br>
<tt><font face="Courier New">mapDoc.Save(xmlStream);</font></tt></span></font><br>
<br>
If your stream starts with:<font size=2 face="Courier New"><span
style='font-size:10.0pt;font-family:"Courier New"'><br>
<tt><font face="Courier New">byte[] { 0xEF 0xBB 0xBF };</font></tt><br>
</span></font>you must remove those three bytes.<br>
<br>
You can then get the byte array by: <br>
<tt><font size=2 face="Courier New"><span style='font-size:10.0pt'>byte[]
utf8EncodedXml = xmlStream.ToArray();</span></font></tt><br>
<br>
And finally:<br>
<tt><font size=2 face="Courier New"><span style='font-size:10.0pt'>MgByteSource
byteSource = new MgByteSource(utf8EncodedXml , utf8EncodedXml.Length);</span></font></tt><font
size=2 face="Courier New"><span style='font-size:10.0pt;font-family:"Courier New"'><br>
<tt><font face="Courier New">byteSource.SetMimeType(MgMimeType.Xml);</font></tt></span></font><br>
