striping unwanted characters from $string part.2

Many thanks to those that replied with my previous query. However the problem continues in another guise. Here is my link: print("<a href=\"javascript:openWin5('tellafriend.php?id=$siteid&title=$sitetitle')\"> <img src='images/image_icons/edit.gif' border='0'> $tell_a_friend</a>;"); The problem is with the $title variable. If the $title contains things like: Müller Amoré then the ü and é look very ugly in any dynamically generated links changeing to things like %33 etc, and any word like: nation¹s We're break the link, is there a way that I can strip the ''s and automatically change things like ü and é to u and e ? Many thanks once again James
