Description

Pass a string into the unescapeHtml() method that contains a hex entity (i.e.
· instead of ·) and you will get a NumberFormatException. The
offending code is in Entity.java, line 690. It should check whether the
character after the # is 'x' and if so, prefix it with '0' and call
Integer.decode().intValue() (or some other hex converting function).

Hex entities are valid HTML
(http://www.htmlhelp.com/reference/html40/entities/latin1.html) so this should
be supported.
