Sure sounds like a byte-order mark. Your question is unclear, but if actually do need to write these files from C# without a byte-order mark, you can specify this by passing false to the UTF8Encoding constructor:

XmlDocument xmlDoc = your_xml_document;
using (TextWriter writer = new StreamWriter(output_filename, new UTF8Encoding(false))
{  
    xmlDoc.Save(writer);
}
