            //Retrieves the translated content

            String content;

            try {

                content = URLDecoder.decode(translationJson.getString("translation"), "utf-8");

            } catch (UnsupportedEncodingException e) {

                String data = translationJson.getString("translation");

                data = data.replaceAll("%(?![0-9a-fA-F]{2})", "%25");

                data = data.replaceAll("\\+", "%2B");

                content = URLDecoder.decode(data, "utf-8");

            } catch (Exception e) {

                content = translationJson.getString("translation");

            }

            translate.setTranslatedContent(content);
