httpclient3上传中文文件问题，目前乱码，请问如何转码，代码如下

public boolean uploadPkg(String uploadFilePath) throws Exception {
    MultipartPostMethod filePost;
    String uploadURL = "/eosmgr/eos/Deploy.jsp?command=upload";
    filePost = new MultipartPostMethod(uploadURL);
    filePost.addParameter("uploadfile", new File(uploadFilePath));
    client.getHttpConnectionManager().getParams()
            .setConnectionTimeout(5000);
    int status = client.executeMethod(filePost);
    if (status != 200) {
        logger.info("上传失败! return status : " + filePost.getStatusLine());
        return false;
    }
    try {
        filePost.releaseConnection();
        logger.info("上传成功!");
    } catch (Exception e) {
        logger.info("上传失败!错误信息：" + e.getMessage());
        return false;
    }
    return true;
}

目的服务器locale出来是GBK,源服务器可能在windows也可能在GBK的linux环境。
