This is the default LC_CTYPE locale type I see on Windows10 and Python 3.7.1 vs 3.5.2: Same: 'C'


'3.7.1 (v3.7.1:260ec2c36a, Oct 20 2018, 14:57:15) [MSC v.1915 64 bit (AMD64)]'

import _locale
_locale.setlocale(_locale.LC_CTYPE, None)

'C'


'3.5.2 (v3.5.2:4def2a2901a5, Jun 25 2016, 22:18:55) [MSC v.1900 64 bit (AMD64)]'

import _locale
_locale.setlocale(_locale.LC_CTYPE, None)

'C'
