You should be able to just leave the BOM, if you like, and tell the browser that you're sending UTF-8. (This is because UTF-8 is the same as 7 bit ASCII (for the first 128 chars).) As you're using some version of Apache, just changing this line in your httpd.conf should be enough I believe:
If you do not have access to the httpd.conf, try putting the following on the actual web page, inside the <head> section:
Lastly, you should have a document type at the top of your web page anyways (as the first line, before the <html> tag). Something like:
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
Just google DOCTYPE for info.
<!DOCTYPE HTML PUBLIC
"-//W3C//DTD HTML 4.01 Transitional//EN"
Anyways, here's the header your server is sending:
