Android post請求轉義字符

Question

如何在字符串中轉義字符「ü」。

我有我的JSON數據這個角色：

{"Name": "Hyüsin"} 

，當我在我的Android的網絡服務器做HttpPost。它給我一個「錯誤的請求」錯誤作爲迴應。

HttpPost代碼：

// uploads the data 
public class UploadData extends AsyncTask<String, Integer, Boolean> { 

     @Override 
     protected Boolean doInBackground(String... url) { 

      try { 

       HttpPost request = new HttpPost(LogInActivity.SERVICE_URI + url[0]); 

       request.setHeader("Content-type", "application/json; charset=utf-8"); 


       //THIS IS {"Name": "Hyüsin"}    
       JSONObject jsonTaakkaart = taakkaart.serializeToObj(); 




       StringEntity entity = new StringEntity(jsonTaakkaart .toString()); 
       request.setEntity(entity); 


       DefaultHttpClient httpClient = new DefaultHttpClient(); 
       HttpResponse response = httpClient.execute(request); 


       return true; 

      } catch (Exception e) { 
       e.printStackTrace(); 
       return false; 
      } 

     } 
    }

用途：

StringEntity entity = new StringEntity(jsonTaakkaart.toString(), "UTF-8"); 

指定編碼是UTF-8。
