The json_encode and the json_decode functions bug with the degree character ( '?' ). 

Reproduce code:
header("content-type: text");
$test = array();
$test['data'] = "test1?test2";
echo json_encode($test) . "\r\n";

Expected result:
stdClass Object
    [data] => test1?test2

Actual result:

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at and the instructions on how to report
a bug at

json functions accepts only valid UTF-8 characters. ASCII characters are UTF-8 compatible, but I guess '?' is not.
