continuing to guess based on python's documentation (here: the "locale"
module[1]):
  .sort(key=locale.strxfrm)

Taking a closer look at locale: probably you need to call "locale.resetlocale()"
before, in order to switch to the locale defined via the environment variables.

Personally I would either trust python's locale implementation or conduct some
experiments :)
