While page encoding is different with content type encoding declaration. Jsoup will get wrong text decode content. To avoid this problem, Assign a correct text encoding will be required.
Connection connection = Jsoup.connect(requestUrl)
.data("type", "1")
.data("searchKeyUID", searchKeyUID)
.timeout(timeout)
.method(Connection.Method.GET);
Connection.Response response = connection.execute();
Document document = Jsoup.parse(new ByteArrayInputStream(response.bodyAsBytes()), "UTF-8", requestUrl);
