UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd3 in position 13: invalid continuation byte
解决方法：
1 确保python文件为utf-8编码，可以使用nodepad++更改，也可以使用pycharm更改，这里是pycharm更改。
File->Setting->Editor->File Encoding
这样就设置成功了，
使用flask读取指定html文件夹目录设置
template_folder参数可以指定读取html模板路径
解决去取html文件失败utf-8问题：
使用nodepad++ 将文件更改为utf-8编码，
操作：将文件内容全复制，然后更改文件编码，删除原来数据，粘贴复制的数据，进行报错就可以
