[jspSmartUpload]------------>jspSmartUpload上传中文文件名 乱码问题
用jspSmartUpload做文件上传下载，该组件默认是不是utf-8编码，对中文支持不好，当文件名或参数有中文时候就会出现乱码。在google一番后找到一种目前比较好的解决方案

找到源码，并且参考网上的讲法，进行修改，发现可以解决

1）当页面上传有参数时，中文会乱码，解决页面上中文参数乱码方法：
修改类SmartUpload()中的upload()方法
(可以按照关键字   application/x-macbinary  定位到)

    public void upload()
        throws SmartUploadException, IOException, ServletException
