Bug description:Vertical tabs ignored by XMLWriter
Description:
------------
When text contains vertical tabs, XMLWriter silently ignores them and
generates invalid XML. This is not an issue where the text is invalid
UTF-8. It is valid UTF-8 data. Vertical tabs are simply not allowed in XML
by rule. I would expect XMLWriter to encode it as it would any other
character not allowed in XML. I suspect that
Test script:
---------------
<?php
$xml = new XmlWriter();
$xml->openMemory();
$xml->startDocument('1.0', 'UTF-8');
$xml->writeElement("test", "This data contains a \vvertical tab");
$xml->endElement();
$data = $xml->outputMemory(true);
$sxml = simplexml_load_string($data);
?>
Expected result:
----------------
Either an error or valid XML.
Actual result:
--------------
Invalid XML is silently created. For example, SimpleXML::addchild() throws
a warning: SimpleXMLElement::asXML(): xmlEscapeEntities : char out of range
when a vertical tab is present and the node is not added.
