UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcf in position 4: invalid continuation byte

Answer 1

Your username is most likely in Russian or the computer name. Therefore, the user folder is in Russian and most likely django is installed globally.
You need to install django in virtualenv in a folder in English, not globally. Then the username in Russian will not affect.
The computer name is changed through the control panel > system > advanced system settings > computer name.

Answer 2

The main error is:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcf in position 4: invalid continuation byte
Your encoding is either wrong or the character is not valid, for example Russian comments.

Answer 3

Cyrillic on Windows crap PC
name
User
name Launch directory name
...
I always did not understand why people use Windows - there are no ideas yet other than masochism

Answer 4

Thank you dear friends! The solution to the problem was suggested to me by asd111! Due to several hard rebuds in the system, "-PC" was assigned to the Latin name of the computer (xs like)! After removing that from the name, everything fell into place!
