Description:
------------
Hi, 

I got the following array and want to enode it to json format:

print_r($hier);

------
 ["ID"]=>  int(254) ["XYID"]=>  int(4) ["Inhalt"]=>  string(127) "@hallowas geht " ["Name"]=>  string(4) "falti" ["Datum"]=>  string(19) "2010-02-06 17:57:54" ["Gru?"]=>  string(14) "TOOTO|??|MOOTO" ["Affe"] => string (4) "Pans"
------  

but the result was 

print_r(json_encode($hier));
----
{"ID":254,"XYID":4,"Inhalt":"@hallowas geht ","Name":"falti","Datum":"2010-02-06 17:57:54","Gru?":null,"Affe":"Pans"}
---  

As you can see the string with the '?' char results a null in the encoded JSON. I uses the option Paramters (JSON_HEX_TAG|JSON_HEX_APOS|JSON_HEX_QUOT|JSON_HEX_AMP) but nothing solved the problem, when I used other chars instead it worked properly.

I saw someone having this Problem on a Linux and MacOs Machine with PHP 5.3 but the bug is still there on Windows machines with PHP 5.3.1

Reproduce code:
---------------
print_r($hier);

------
 ["ID"]=>  int(254) ["XYID"]=>  int(4) ["Inhalt"]=>  string(127) "@hallowas geht " ["Name"]=>  string(4) "falti" ["Datum"]=>  string(19) "2010-02-06 17:57:54" ["Gru?"]=>  string(14) "TOOTO|??|MOOTO" ["Affe"] => string (4) "Pans"
------  
results:

print_r(json_encode($hier));
----
{"ID":254,"XYID":4,"Inhalt":"@hallowas geht ","Name":"falti","Datum":"2010-02-06 17:57:54","Gru?":null,"Affe":"Pans"}
---  

Expected result:
----------------
print_r($hier);

------
 ["ID"]=>  int(254) ["XYID"]=>  int(4) ["Inhalt"]=>  string(127) "@hallowas geht " ["Name"]=>  string(4) "falti" ["Datum"]=>  string(19) "2010-02-06 17:57:54" ["Gru?"]=>  string(14) "TOOTO|??|MOOTO" ["Affe"] => string (4) "Pans"
------  

but the result was 

print_r(json_encode($hier));
----
{"ID":254,"XYID":4,"Inhalt":"@hallowas geht ","Name":"falti","Datum":"2010-02-06 17:57:54","Gru?":"TOOTO|??|MOOTO","Affe":"Pans"}
---  

Actual result:
--------------
print_r(json_encode($hier));
----
{"ID":254,"XYID":4,"Inhalt":"@hallowas geht ","Name":"falti","Datum":"2010-02-06 17:57:54","Gru?":null,"Affe":"Pans"}
