Dear Experts,
XElement objEl =XElement.Load(Filename);objEl.Save(Filename);
after the file is saved the saved file have these 3 characters  , ascii vales[239,187,191]
why these 3 charachteres are added on file save ?
this charachters are not visible in notepad, but if file is opened in EDIt.com then only they can be seen.
trouble is that if i submit this file to our Excise (TAX) Department for whom it is generated it gets rejected and certainly why this unknown addition to file is there ?
