UnicodeDecodeError ao iniciar um novo projeto Django no Windows

Eu crio um novo projeto em Django usando PyCharm. Eu não altero nada. Ao iniciar o projeto, ocorre o erro:

""C:\\Program Files (x86)\\JetBrains\\PyCharm 5.0.3\\bin\\runnerw.exe""
c:\\python34\\python.exe e:/projects/proj_test/manage.py runserver 8000
