simplexml utf-8 issues

[tablatronix]

We do not save all our xml as utf-8
for example user.xml files
$xml = new SimpleXMLElement('<item></item>');

usually we do
$xml = new SimpleXMLExtended('<?xml version="1.0" encoding="UTF-8"?><item></item>');
for cdata support and utf-8 encoding

I suggest we extend SimpleXmlElement or always use extended and
add wrapper functions to create new xml elements for GS in it.

example usage, not actual

I do not know if its possible to modify the constructor... its final

class myclass extends SimpleXMLElement { 
    static function make($data, $xmlVersion='1.0', $xmlEncoding='ISO-8859-1', $rootName='root'){ 
        $obj=parent::__construct($data); 
        $obj->x=$xmlVersion;
        $obj->e=$xmlEncoding;
        $obj->r=$rootName;

        return $obj;
    } 
}

// or 

class myclass extends SimpleXMLElement {
   public static function getInstance($xmlversion = '1.0', $xmlencoding = 'ISO-8859-1', $rootName='root') {
      return new self("<?xml version='$xmlVersion' encoding='$xmlEncoding'?><$rootName />");
   }
}

I have updated all extended objs, but i missed ones using the native class
