Comment (by AmbushCommander):

 Hi, this is the lead developer for HTML Purifier. The upcoming, newest
 version of HTML Purifier does in fact handle this case gracefully by
 changing the unescaped < into a literal. For your case, however, with one
 simple regex:

 $html = preg_replace('/<([^A-Za-z0-9])/', '&lt;$1', $html);

 No mucking around kses necessary. This, however, will turn < br> into &lt;
 br&gt;
