[jira] [Commented] (TEXT-44) NumericEntityUnescaper.translate throws an IllegalArgumentException if entityValue > MAX_CODE_POINT

    [ https://issues.apache.org/jira/browse/TEXT-44?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15778632#comment-15778632 ] 

Pascal Schumacher commented on TEXT-44:
---------------------------------------

Issue moved from commons-lang to commons-text, because WordUtils was ported to commons-text and and the commons-lang version will soon be deprecated.

> We found that using the function StringEscapeUtils.unescapeHtml4 crashes if the argument is "&#14844069;" 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.
