Alamofire 4 and special characters in JSON

I've got a problem with special characters with Alamofire 4.
The JSON contains æ, ø and å and the browser shows them fine, also my previous solution using SwiftyJSON did.

Alamofire 4 shows something like this instead:

U00e6 

Using this call:

Alamofire.request(specificURL, method: .get, parameters: param, encoding: URLEncoding.default, headers: nil).responseJSON { (response: DataResponse<Any>) in     print(response) } 

What to do to solve this?

Edit:

Alamofire.request(url, method: .get, parameters: param, encoding: JSONEncoding.default)         .responseJSON { response in              switch response.result {             case .success(let value) :                  print(response.request)  // original URL request                 print(response.response) // HTTP URL response                 print(response.data)     // server data                 print(response.result)   // result of response serialization                  if let JSON = response.result.value as! [String:AnyObject]!{                     print("JSON: ",JSON)                     self.arrUser = Mapper<Users>().mapArray(JSONArray:JSON["user"] as! [[String : Any]])!                     self.tableView.reloadData()                 }             case .failure(let encodingError):                 //Print error             }     } 

I got the issue that I have added æ in json response and try to print.

Output:

JSON:  Optional(<__NSArrayI 0x600000050320>( {     "email_address" = "testwts06@gmail.com";      username = "testwts06 \U00e6"; }, {     "email_address" = "testwts01@gmail.com";     username = "testwts01 \U00eb"; }, {     "email_address" = "testwts100@gmail.com";     username = testwts100; }) 

While displaying it display in correct format.

Swift 3 update for Ekta's answer:

let encodedURL = specificURL.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed)

Seems the typical serialization error due to wrong JSON encoding, probably your response status code is 3840.

JSON text SHALL be encoded in UTF-8, UTF-16, or UTF-32.

You could try to convert the response data to correct UTF8 encoding:

let datastring = NSString(data: response.data!, encoding: String.Encoding.isoLatin1.rawValue) let data = datastring!.data(using: String.Encoding.utf8.rawValue) do {      let object = try JSONSerialization.jsonObject(with: data!, options: .allowFragments)      let jsonDic = object as! NSDictionary      print("  ok, successfully converted..\(jsonDic)") } catch let aError as Error {      // print and handle aError  } 

Hope it helps you.

Here is a simple String extension that solves the issue:

extension String {     func fixUnicode() -> String {         var copy = self as NSString         let regex = try! NSRegularExpression(pattern: "\\\\U([A-Z0-9]{4})", options: .caseInsensitive)         let matches = regex.matches(in: self, options: [], range: NSMakeRange(0, characters.count)).reversed()         matches.forEach {             let char = copy.substring(with: $0.rangeAt(1))             copy = copy.replacingCharacters(in: $0.range, with: String(UnicodeScalar(Int(char, radix: 16)!)!)) as NSString         }         return copy as String     } }
