You may need to specify your charset at the VERY START of your page: something like:
$charset='iso-8859-1'; //I have NO IDEA what charset you should be using!!
// figure it out and put it there!!
echo "
<meta http-equiv='Content-Type' content='text/html;charset=$charset' >
";
echo $everything_else_on_your_page;
Some bright poster may know the right charset...
PS: Some Safari versions just ignore the user-specified charset and display whatever they please.
