Django in Windows

The following error appears when running the runserver with the long-range setting set.

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb9 in position 5: invalid start byte

I know it's an encoding error, but how do I fix it?

The complete error log is below.

Quit the server with CTRL-BREAK.
