Send mails in UTF-8..

In domain/UbMain.php the function sendMail() sends in charset iso-8859-1 which can problems with some languages like French for example.
Could you change it by something like that: $headers .= ‘Content-type: text/html; charset=’.get_option(‘blog_charset’). “\r\n”;

If it could help you here is what un modify:

public function sendMail($linkpartner, $id) {
        ob_start();
        require_once(UB_PLUGIN_DIR."gui".DIRECTORY_SEPARATOR."Mail.php");
        $body = ob_get_clean();
        $headers  = 'MIME-Version: 1.0' . "\r\n";
        $headers .= 'Content-type: text/html;' . "\r\n";
         $headers .= 'From: WordPress Ultimate Blogroll <'.get_bloginfo('admin_email').'> '."\r\n";
         $subject = __("New link submitted at", "ultimate-blogroll")." ".home_url().''."\r\n";
        if(function_exists('wp_mail')):
            add_filter('wp_mail_charset',create_function('', 'return \''.get_option('blog_charset').'\'; '));
            wp_mail(UbMapper::getInstance(UbMapper::Settings)->getConfig("blogroll_contact"), $subject, $body, $headers);
        else:
            mail(UbMapper::getInstance(UbMapper::Settings)->getConfig("blogroll_contact"), $subject, $body, $headers);
        endif;
