Description:
------------
So, I have an array witch doesn't encode right in json...
( look the example script... )

Test script:
---------------
$a = Array (
    "password" => "SeRjQRVUglkeM‰‰P9L7NsjKXOY", //it's encrypted with a custom encryption system
    "id" => 0
);
echo json_encode($a);

Expected result:
----------------
{"password":"SeRjQRVUglkeM‰‰P9L7NsjKXOY","id":0}

Actual result:
--------------
{"password":null,"id":0}
