    By default, some web browsers unfortunately do not include the territory
    in the locale identifier for many locales, and some don't even allow the
    user to easily add the territory. So while you may prefer using qualified
    locale identifiers in your web-application, they would not normally match
    the language-only locale sent by such browsers. To workaround that, this
    function uses a default mapping of commonly used langauge-only locale
    identifiers to identifiers including the territory:
    
    >>> negotiate_locale(['ja', 'en_US'], ['ja_JP', 'en_US'])
    'ja_JP'
    
    Some browsers even use an incorrect or outdated language code, such as "no"
    for Norwegian, where the correct locale identifier would actually be "nb_NO"
    (Bokmål) or "nn_NO" (Nynorsk). The aliases are intended to take care of
    such cases, too:
    
    >>> negotiate_locale(['no', 'sv'], ['nb_NO', 'sv_SE'])
    'nb_NO'

    dictionary to this function, or you can bypass the behavior althogher by
