How to remove invisible junk characters from a XML file
<p>I want to read some xml files.</p>

<p>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 "<strong>∩╗┐</strong>" is seen.
I think '<strong>∩╗┐</strong>' is creating an error.i am finding the error  “Content is not allowed in prolog.”</p>

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

<p>Thanks in advance.</p>
