Font problem maybe ??
When I went to your site, I could see the characters, then displayed the source code, and could _just_ see those characters before this html code
DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
so, .. at a guess those characters are being echoed from index.php, before the html code. Search through your files locally (on your PC), and look for the character ""
