If you access the following website in IE / Firefox, you can view the site perfectly. However, with Chrome / Safari, you can't. You just see a bunch of code with ascii question marks. I know it's missing the doctype declaration, but is it the question marks that make it not visible for those browsers? (Chrome / Safari)

When the site's pages are opened in notepad, textpad and notepad++, the question marks aren't there... so how do you eliminate them? Does anybody know of another editor that will view / edit these? Does anybody know if that's even the problem? How did they just appear out of nowhere?

Most importantly; How would YOU fix this problem in the easiest way possible? (I'm guessing a certain type of text editor with a search function, then search / eliminate them and re-save the file?)

Any help is MUCH appreciated! Thank you so much in advance for your time!
