问题描述：

1.下载下来压缩包解压之后，文件名出现乱码，文件内容是正常的

2.原文件名的编码也是utf8......

   执行convmv -r -f gbk -t utf8 *  文件名转换之前的测试（这里预判文件名为gbk编码）

   结果，文件名也是utf-8的，具体原因不知，有可能是en_us.utf8和zh_cn.utf8的区别，

  系统默认使用的en_us.utf8字符集

        Skipping, already UTF-8......

$ convmv -r -f gbk -t utf8 *

No changes to your files done. Would have converted 0 files in 0 seconds.
Use --notest to finally rename the files.

解决：

首先，安装一下文件名编码转换工具convmv

         sudo apt install convmv

第一步，先把文件名从utf8转换到iso88591

                执行：convmv -r -f utf8 -t iso88591 * --notest 

$ convmv -r -f utf8 -t iso88591 * --notest
