​This is a great custom plugin we came across that will automatically format any field in ExpressionEngine.

Create a “util” folder and a php file named pi.util.php for the plugin.

Put the “util” folder in expressionengine/third_party/

    public function htmlspecialchars() {
        $this->EE = &get_instance();
        return htmlspecialchars($this->EE->TMPL->tagdata);
