Thomas Neidhart commented on LANG-898:
--------------------------------------

Afaik, it is not mandatory to escape CR & LF in xml documents, thus it is also 
not done by default when calling StringEscapeUtils.escapeXml.

You can create your own translater that will also escape LF like this:

{noformat}
StringEscapeUtils.ESCAPE_XML.with(NumericEntityEscaper.between(0x09, 
0x11)).translate(...);
{noformat}

> In an escaped XML string with escaped whitespace, in this case linefeed (

 ), escapexml and unescapexml treat the linefeed inconsistently.

 to a linefeed, yet escapexml does not convert
