字节数组与一些中文字符串

Question

我正在将字节数组转换为字符串，它包含一些中文字符但我无法正确显示。我从我使用UTF-8的数据库加载它。

代码：

            String url = params[0];
            HttpClient client = new DefaultHttpClient();
            HttpResponse response;
            long fileSize = 0;
            int downloadSize = 0;
            String jsonStr = "";            

            try {
                response = client.execute(new HttpGet(url));
                StatusLine status = response.getStatusLine();
                if (status.getStatusCode() == HttpStatus.SC_OK){
                    fileSize = response.getEntity().getContentLength();

                    InputStream inputStream = response.getEntity().getContent();
                    byte[] buffer = new byte[1024];
                    int numByteRead = 0;

                    BufferedOutputStream outputStream = new BufferedOutputStream(new ByteArrayOutputStream());
                    while ( (numByteRead = inputStream.read(buffer)) > 0){
                        outputStream.write(buffer, 0, numByteRead);
                        jsonStr += new String(buffer, "UTF-8");
                        downloadSize += numByteRead;
                        Log.i(SUBTAG, "downloadSize/fileSize: "+downloadSize+"/"+fileSize);
                    }

                    Log.d(SUBTAG, "jsonStr: "+jsonStr);
                } else {
                    Log.e(SUBTAG, "connection problem : "+status.getStatusCode());
                    finish();
                }

            } catch (IOException e) {
                // TODO Auto-generated catch block
                Log.e(SUBTAG, "connection failed : "+e);
                finish();
            }

以及我得到的结果：
