JSON Serialize Emoji

I need to send a message to the server which contains emojis. I read the data from CoreData, store it in dictionary and then convert it into json format.

My initial dictionary has following content

["0": ["chat_token": "8g9nu0Z.a3", "message": "🤛👌", "user_id": "1242", "created": "2017-12-29 17:13:16"]]

I then convert it into JSON using following code

do {
    let jsonData = try JSONSerialization.data(withJSONObject: resultDict, options: [])
    if let jsonText = NSString(data: jsonData, encoding: String.Encoding.ascii.rawValue) {
        return jsonText as String
    }
} catch let error {
    print(error)
}

This returns me following json string

{"0":{"chat_token":"8g9nu0Z.a3","message":"ð¤ð","user_id":"34","created":"2017-12-29 17:13:16"}}

The problem is emojis are not correctly formatted. In JSON it gets converted to ð¤ð

The reason I need it is to send it to the server to store the message. How do I convert emoji to json string format.

The issue is that you are trying to initialize the String with ASCII encoding, in which emojis doesn't exist. You should be using UTF-8.

You also shouldn't be using NSString, since you are returning a String anyways and aren't using any NSString specific functionality.

do {
    let jsonData = try JSONSerialization.data(withJSONObject: resultDict)
    if let jsonText = String(data: jsonData, encoding: .utf8) {
        return jsonText
    }
} catch let error {
    print(error)
}

Output:

"{"0":{"chat_token":"8g9nu0Z.a3","message":"🤛👌","user_id":"1242","created":"2017-12-29 17:13:16"}}"
