    Description

      We found that using the function StringEscapeUtils.unescapeHtml4 crashes if the argument is "�" and throws an IllegalArgumentException.

      This happens because internally it calls the function NumericEntityUnescaper.translate and doesn't check if the value is bigger than 0x10FFFF (MAX_CODE_POINT) that is a check inside Character.toChar.

      Maybe we need to check that the entity value is less than Char.MAX_CODE_POINT.
