You cannot use brackets () in the value of an entity attribute

Question

I have been experimenting with Orion for the past few days, and after a while I did it as planned.

I came across unexpected annoyance, although the string attribute for the given entity context will not be able to register.

Example:

http POST [my_orion_server_url]:1026/v1/updateContext < create_push.json

Where create_push.json:

{
    "contextElements": [
        {
            "type": "Push",
            "isPattern": "false",
            "id": "Push1",
            "attributes": [
                {
                    "name": "message",
                    "type": "string",
                    "value": "this is a test)"
                }
            ]
        }
    ],
    "updateAction": "APPEND"
}

The server responds:

HTTP/1.1 200 OK
Content-Length: 129
Content-Type: application/json
Date: Thu, 19 Nov 2015 11:47:03 GMT

{
    "errorCode": {
        "code": "400", 
        "details": "Illegal value for JSON field", 
        "reasonPhrase": "Bad Request"
    }
}

If, on the other hand, I remove the brackets, everything works as expected:

Json file:

{
    "contextElements": [
        {
            "type": "Push",
            "isPattern": "false",
            "id": "Push1",
            "attributes": [
                {
                    "name": "message",
                    "type": "string",
                    "value": "this is a test"
                }
            ]
        }
    ],
    "updateAction": "APPEND"
}

Server response:

{
    "contextResponses": [
        {
            "contextElement": {
                "attributes": [
                    {
                        "name": "message", 
                        "type": "string", 
                        "value": ""
                    }
                ], 
                "id": "Push1", 
                "isPattern": "false", 
                "type": "Push"
            }, 
            "statusCode": {
                "code": "200", 
                "reasonPhrase": "OK"
            }
        }
    ]
}

Is this scheduled or a mistake?

I can overcome the problem encoding brackets with something else, and then decode on reception, but the ability to send brackets directly with the entity will be smoother and less annoying.
