Я пытаюсь выполнить createsuperuser от Django и получаю следующую ошибку. Ранее база данных syncdb была пуста и закодирована в ‘utf-8’. Я использую pymysql.

 D:Python27sitemysite>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

Байт с кодом C0 недопустим в тексте, закодированном в UTF-8. Я не знаю, откуда взят этот текст, но это либо недопустимый UTF-8, либо ваш код ошибочно пытается обработать его как UTF-8.
