<form>s: +accept-charset="iso-8859-2"

 - fixed CSacek-2.1.9-incompatibility
   - temporary workaround, to be removed when CSacek supports input "utf-8"
 - fixed (cosmetic IRL) HTML-4.01 non-compliance
 - for more details see common.php/form_charset()
<form>s: +enctype="application/x-www-form-urlencoded"
 - should be default (HTML-4.01), just to be sure
