Getting question marks in service response in codenameone - connection

Question

I am calling service using ConnectionRequest class and if i'm getting result in English i'm able to display it but if i'm getting response in Hindi at that time getting as question marks(?) instead of Hindi text. and i'm using Devanagari Font to show the hindi text. is there any solution for this?
here is the code for how we are requesting?
adding parameters using Map like below.
Map<String, Object> map = new HashMap<String, Object>();
map.add("Key","Value");
map.add("Key1","Value1");
etc..
then passing this map object to requestService method.
private static Map<String, Object> requestService(Map<String, Object> data) {
Connection connection = null;
Dialog progress = new InfiniteProgress().showInifiniteBlocking();
try {
connection = new Connection(data);
NetworkManager networkManager = NetworkManager.getInstance();
networkManager.addToQueueAndWait(connection);
networkManager.setTimeout(600000);
if(connection.getResponseData() == null) {
return null;
}
} finally {
progress.dispose();
}
JSONParser jp = new JSONParser();
try {
Map<String, Object> result = jp.parseJSON(new InputStreamReader(new ByteArrayInputStream(connection.getResponseData()), "UTF-8"));
return result;
} catch (Throwable e) {
e.printStackTrace();
}
return null;
}
Connection Class:
private static class Connection extends ConnectionRequest {
private final static char escapeS[] = new char[] { '"', '\\', '/', '\b', '\f', '\n', '\r', '\t' };
private final static char escapeR[] = new char[] { '"', '\\', '/', 'b', 'f', 'n', 'r', 't' };
private Map<String, Object> data;
private Connection(Map<String, Object> data) {
this.data = data;
setFailSilently(true);
setPost(true);
setWriteRequest(true);
setContentType("application/json");
setUrl(serverUrl);
}
#Override
protected void buildRequestBody(OutputStream os) throws IOException {
String v = buildJSON(data);
if(shouldWriteUTFAsGetBytes()) {
os.write(v.getBytes("UTF-8"));
} else {
OutputStreamWriter w = new OutputStreamWriter(os, "UTF-8");
w.write(v);
}
}
private static String buildJSON(Map<String, Object> data) {
StringBuilder json = new StringBuilder();
buildJSON(data, json);
return json.toString();
}
#SuppressWarnings("unchecked")
private static void buildJSON(Map<String, Object> data, StringBuilder json) {
json.append('{');
boolean first = true;
Object value;
for(String key: data.keySet()) {
value = data.get(key);
if(value == null) {
continue;
}
if(first) {
first = false;
} else {
json.append(",");
}
json.append('"').append(key).append("\":");
if(value instanceof Map) {
buildJSON((Map<String, Object>) value, json);
} else if(value instanceof Collection) {
buildJSON((Collection<Map<String, Object>>)value, json);
} else {
if(value instanceof Long || value instanceof Integer || value instanceof Double
|| value instanceof Short || value instanceof Float) {
json.append(value);
} else if(value instanceof Boolean) {
json.append((Boolean)value ? "true" : "false");
} else {
json.append('"').append(escape(value)).append('"');
}
}
}
json.append('}');
}
private static void buildJSON(Collection<Map<String, Object>> data, StringBuilder json) {
json.append('[');
boolean first = true;
for(Map<String, Object> e: data) {
if(first) {
first = false;
} else {
json.append(",");
}
buildJSON(e, json);
}
json.append(']');
}
private static String escape(Object any) {
if(any == null) {
return "";
}
String s = any.toString();
if(s == null) {
return "";
}
for(int i = 0; i < escapeS.length; i++) {
s = replace(s, escapeS[i], escapeR[i]);
}
return s;
}
private static String replace(String s, char c, char r) {
int i = s.indexOf(c);
if(i < 0) {
return s;
}
return s.substring(0, i) + "\\" + r + replace(s.substring(i + 1), c, r);
}
}
please guide me to achieve this?

That means the result is encoded in a foreign language encoding and should be read using the correct hindi text encoding.
