Message 309987 - Python tracker

Test on Linux (Fedora 27, glibc 2.26):

locale.setlocale(locale.LC_ALL, "fr_FR")
locale.setlocale(locale.LC_NUMERIC, "es_MX.utf8")

It works as expected, result:

decimal_point: '.'
thousands_sep: '\u2009'

Python 3.6 returns mojibake:

decimal_point: '.'
thousands_sep: '\xe2\x80\x89'

Python 2.7 raw strings, thousands_sep = b'\xE2\x80\x89'.
