If there are html entities (i.g. ö ) in title tag of tracked page,the entities sometimes doesn't show correctly in Page titles widget. Please look in attachement.
Maybe a html_entity_decode is missing.

The ampersand is encodeURIComponent()'d for transmission. This would actually require getRequestVar() to sanitize with something like:
$x = htmlspecialchars(html_entity_decode(htmlspecialchars_decode($x)));
