ZF-6670: Zend_Json_Encoder::encodeUnicodeString is missing


The encodeUnicodeString static method of Zend_Json_Encoder is missing. It is called into the new method Zend_Json::_recursiveJsonExprFinder

Here is a fix :

public static function encodeUnicodeString($string) {
    $encoder = new self();
    return substr($encoder->_encodeString($string), 1, -1);


I think you might have include path problems. for me the method is there, and unittests run without problems.
