/**
* Prepares a new XML parser.
*
* This is a wrapper around xml_parser_create() which extracts the encoding
* from the XML data first and sets the output encoding to UTF-8. This function
* should be used instead of xml_parser_create(), because PHP 4's XML parser
* doesn't check the input encoding itself. "Starting from PHP 5, the input
* encoding is automatically detected, so that the encoding parameter specifies
* only the output encoding."
*
* This is also where unsupported encodings will be converted. Callers should
* take this into account: $data might have been changed after the call.
*
* @param $data
* The XML data which will be parsed later.
*
* @return
* An XML parser object or FALSE on error.
*
* @ingroup php_wrappers
*
* @deprecated in drupal:8.3.0 and is removed from drupal:9.0.0. Use
* xml_parser_create() and
* xml_parser_set_option($xml_parser, XML_OPTION_TARGET_ENCODING, 'utf-8')
* instead.
