They are trimming in title div section.

<div class="SubTab">Discussion title part in url keeps leading and trailing spaces as hyphen</div>

And only leading spaces are trimming in title tag (trailing spaces are kept).

<title>Discussion title part in url keeps leading and trailing spaces as hyphen  - Vanilla Forums</title>

It's not a big issue but feel bit strange when you copy & paste url.
So I think Url function is better like this.

// Better Unicode support
$Mixed = strip_tags(html_entity_decode($Mixed, ENT_COMPAT, 'UTF-8'));
$Mixed = strtr($Mixed, self::$_UrlTranslations);
$Mixed = preg_replace('`([^\PP.\-_])`u', '', $Mixed); // get rid of punctuation
$Mixed = preg_replace('`([^\PS+])`u', '', $Mixed); // get rid of symbols
$Mixed = preg_replace('`^\s+|\s+$`u', '', $Mixed); // remove leading and trailing spaces
$Mixed = preg_replace('`[\s\-/+]+`u', '-', $Mixed); // replace certain characters with dashes
$Mixed = rawurlencode(strtolower($Mixed));
return $Mixed;
