UnicodeDecodeError: 'cp932' codec can't decode byte 0xef in position 0: illegal multibyte sequence

[Rhaegal]

I install cabocha according to this link:
https://qiita.com/mima_ita/items/161cd869648edb30627b
When I use this command:

python setup.py install

The error is:

E:\Cabocha\cabocha-0.68\cabocha-0.68\python>python setup.py install
Traceback (most recent call last):

How to modify?
