Answer 1

when send your string to server

String encodedString = URLEncoder.encode(yourString, "UTF-8");

when get your string from server

String decodedString = URLDecoder.decode(yourString, "UTF-8");

Answer 2

I'm answering bit late but hope it will help someone else. I faced the same issue and resolved by setting CharacterSet to utf-8 and Content-Type to application/json in my case. You can select other content types as per your requirement. See below

StringEntity s = new StringEntity(data.toString(), "utf-8");
s.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));

Below is the complete method.

public static String doPost(JSONObject data, String url)
            throws ClientProtocolException, IOException, TimeoutException, ApiException {

    HttpParams httpParameters = new BasicHttpParams();
    int timeoutConnection = 30000; // 30 Seconds
    HttpConnectionParams.setConnectionTimeout(httpParameters,
            timeoutConnection);

    int timeoutSocket = 50000;
    HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

    HttpClient httpclient = new DefaultHttpClient(httpParameters);

    HttpPost httppost = new HttpPost(url);
    httppost.addHeader("Authorization", "Basic " + addAuthHeader());

    Log.d("TAG", "Data ==> " + data.toString());

    StringEntity s = new StringEntity(data.toString(), "utf-8");
    s.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));

    httppost.setEntity(s);

    HttpResponse response = httpclient.execute(httppost);
    HttpEntity entity = response.getEntity();
    String status = getASCIIContentFromEntity(entity);


    int statusCode = response.getStatusLine().getStatusCode();
    if (statusCode != HttpStatus.SC_OK) {
        status = "ApiError";
        throw new ApiException();           
    }           

    Log.d("TAG", "Response String ====== " + status);

    return status;
}
