UnicodeDecodeError with "И" letter

[Karpovich-alex]

There is some trouble with "И" letter in comments or strings.
You can reproduce this error with code
print("И")
And you will get
" File "C:\ ...\venv\lib\site-packages\flake8_pytest.py", line 33, in run
noqa = _get_noqa_lines(file_to_check.readlines())
File "C:\ ...\Python\Python310\lib\encodings\cp1251.py", line 23, in decode
return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x98 in position 8: character maps to <undefined>" error.
But with letter "и" it goes well.
