is the BOM or Byte Order Mark of the Unicode standard. To solve issues where the BOM appears on top of your web page, simply open it in a note editor like notepad++ and change formatting to Unicode in UTF-8 without BOM and then save the file.
The BOM should not appear anymore when you view the page on a browser after doing this formatting change.
