             Summary: NumericEntityUnescaper.translate throws an 
IllegalArgumentException if entityValue > MAX_CODE_POINT
                 Key: LANG-1022
                 URL: https://issues.apache.org/jira/browse/LANG-1022
             Project: Commons Lang
          Issue Type: Bug
          Components: lang.text.translate.*
            Reporter: Miquel
            Priority: Minor


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.
