I need help for getting the <charinsert> .... </charinsert> tags working in my local Mediawiki.Copryrightwarning

What I did already

1. copied [1] to my local wiki page:Mediawiki:Copyrightwarning 2. copied [2] from CVS to /mywiki/extensions) 3. command inserted in LocalSettings.php: include ($IP."/extensions/CharInsert.php");

but I still cannot click onto one of the special characters.

Is there anyone who can assist me, please ? T.
