Turkish character problem as a result of my request to api via c #

Hello Everyone

I am requesting an api. The data contains Turkish characters. However, these Turkish characters do not show up in the end. For example , "Türkiye" comes as "T\u00fcrki to"

static string GET(string url)
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            try
            {
                WebResponse response = request.GetResponse();
                using (Stream responseStream = response.GetResponseStream())
                {
                    StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
                    return reader.ReadToEnd();
                }
            }
            catch (WebException ex)
            {
                WebResponse errorResponse = ex.Response;
                using (Stream responseStream = errorResponse.GetResponseStream())
                {
                    StreamReader reader = new StreamReader(responseStream, System.Text.Encoding.GetEncoding("utf-8"));
                    String errorText = reader.ReadToEnd();
                    // log errorText
                }
                throw;
            }
        }
