Simply I have simple connection:

private var socket: SocketIOClient?
socket?.on(event.rawValue) { data, _ in
    if let response = data.first { // it is called✅ for A, but not❌ for B
        handler(JSON(response))
    }
}

Part of data response for A:

{un:31281, Greg Weg} zmieni\U0142(a) saldo wymiany. 23,03 {z} by\U0142o u {un:27583, \Ud83d\Ude42\Ud83c\Udfc6gh fh\Ud83d\Ude28\Ud83e\Udd13\Ud83e\Udd79cvww}, teraz 23,025 {z} jest u {un:27583, \Ud83d\Ude42\Ud83c\Udfc6gh fh\Ud83d\Ude28\Ud83e\Udd13\Ud83e\Udd79cvww}. 

Part of data response for B:

{un:31281, Greg Weg} zmieniU0142(a) saldo wymiany. 23,04 {z} byU0142o u {un:27583, Ud83dUde42Ud83cUdfc6gh fhUd83dUde28Ud83eUdd13Ud83eUdd79cvww}, teraz 23,046 {z} jest u {un:27583, Ud83dUde42Ud83cUdfc6gh fhUd83dUde28Ud83eUdd13Ud83eUdd79cvww}.

are escaped for A, and not for B. Is there a way to resolve this coding?
