# in browser
<script type="text/javascript">

     JSlt=unescape('%3C'); // "<"
     JSgt=unescape('%3E'); // ">"
     document.write(''+JSlt+'a h'+'ref='+'"mai'+'lto:'+'alex'+'@zei'+'tfor'+
                    'm.de'+'"'+JSgt+'al'+'ex@z'+'eitf'+'orm.'+'de'+JSlt+'/'+
                    'a'+JSgt+'');
