How to remove invisible junk characters from a XML file

I want to read some xml files.

when i am opening these files with notepad/wordpad/MS Word or any Browser, it is opening in its original form.But when i tried to execute it with MS DOS, an invisible chacter like “∩╗┐” is seen.
I think ‘∩╗┐‘ is creating an error.i am finding the error “Content is not allowed in prolog.”

Please tell me how can i remove this invisible junk characters from xml file using C# code.

Thanks in advance.

Method 1

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);
}

Method 2

That might be the UTF-8 byte-order mark. Many text editors (for example Notepad++ and jEdit) allow you specify whether the BOM should be written for UTF-8 or not. With Windows Notepad your only option is to save the file as ANSI.
