ftpclient 乱码问题 怎么解决？

   
用的是APACHE的FTPCLIENT， 但文件名中如果有中文， 传到服务器上就乱码了， 
尝试过ftpClient.setControlEncoding("gb2312"); “UTF-8”,"GBK"
都不行， 弄了一半天， 不知道有什么办法吗
 public boolean upload(String path, String fileName, InputStream inputStream) throws IOException {
        boolean flag = false;
        try {
         ftpClient.setControlEncoding("gb2312");
          FTPClientConfig conf = new FTPClientConfig(FTPClientConfig.SYST_UNIX);
             conf.setServerLanguageCode("en");
         ftpClient.cwd(remotePath);
            alertWorkingDirectory(path);
            flag = ftpClient.storeFile(new String(fileName.getBytes("utf-8"), "gb2312"), inputStream);
            if (flag) {
                System.out.println(" upload success !!! ");
            }
           // ftpClient.sendCommand("chmod 777 " +fileName);
        } catch (IOException e) {
            logger.severe("not upload !!!  " +e.getMessage());
            throw new IOException(e);
        }
        return flag;
    }
