Accented letters and emojis

Question

I need to encode/decode emojis, I'm using this code

var encodeEmoji: String{
        if let encodeStr = NSString(cString: self.cString(using: .nonLossyASCII)!, encoding: String.Encoding.utf8.rawValue){
            return encodeStr as String
        }
        return self
    }

For emojis all is fine, but when I'm coding Accented letters (æ, ø, å) I have something like this \346, \370, \345 Could anyone help to avoid converting of Accented letters, or say, what I'm doing wrong. Thanks in advance!

One method is to encode each character separately, detecting Emojis:

let testString = "abcdřšá"

let encoded = testString.unicodeScalars
    .map {
        guard $0.isEmoji else { return String($0) }
        let data = String($0).data(using: .nonLossyASCII, allowLossyConversion: true)!
        return String(data: data, encoding: .ascii)!
    }.joined()

print(encoded) // abcdřšá\ud83d\ude03\ud83d\ude03\ud83d\ude03

Using the isEmoji method from this answer.

Thanks a lot! Great solution – Alexander B Feb 15 '18 at 15:23 — Alexander B, Feb 15 '18 at 15:23
