    TestCase: set locale from the environment
    
    This fixes an annoyance I'd had for a while: UTF-8 arrows etc.
    in debug messages came out as "?", because until we call setlocale()
    we're in the C locale, whose character set is ASCII (and some layer
    of library responds by transcoding our strings into ASCII).
    
    With this change, running the tests in en_GB.UTF-8 results in
    Unicode arrows and more comprehensible output.
