542873 Fix Validation Issue on ZenCart 2 2

I need to fix a validation issue that I don't find how to fix on my Zen Cart and apparently is causing to look horrible on IE8. I will give link on PMB if you ask for it. ERROR: "The Unicode Byte-Order Mark (BOM) in UTF-8 encoded files is known to cause problems for some text editors and older browsers. You may want to consider avoiding its use until it is better supported." I tried converting the files as suggested an many sites but didn't help. Please only programmers knowledgeable of Zen Cart template system and know what they are doing will be considered.
