'utf-8'无法解码位置0中的字节0xc0：无效起始字节

Question

我试图执行Django的createsuperuser并收到以下错误。在syncdb数据库为空之前，在'utf-8'中编码。我使用pymysql。

D:\Python27\site\mysite>python manage.py syncdb 
Creating tables ... 
Creating table auth_permission 
Creating table auth_group_permissions 
Creating table auth_group 
Creating table auth_user_user_permissions 
Creating table auth_user_groups 
Creating table auth_user 
Creating table auth_message 
Creating table django_content_type 
Creating table django_session 
Creating table django_site 

You just installed Django's auth system, which means you don't have any superuse 
rs defined. 
Would you like to create one now? (yes/no): yes

Answer 1

字节与码C0是UTF-8编码的文本invalid。我不知道这个文本来自哪里，但它不是无效的UTF-8，或者你的代码错误地试图把它当作UTF-8。
