    tests: Specify encoding in locale.
    
    On some systems, `local.setlocale` cannot be called with just a
    language code; an encoding must be specified also.  (See the
    documentation at
    https://docs.python.org/3/library/locale.html#locale.setlocale.)
    
    This change specifies an encoding for the locale used in testing,
    which prevents exceptions from being thrown on such systems.
