          @param locale: a string representation of a locale, i.e., a ISO 639-3
             alpha-3 code (or alpha-2 code), optionally followed by a dash
             character ``-`` and a ISO 3166-1 alpha-2 code.
  
          @param strict: indicate whether the string representation of a locale
              has to be strictly compliant with RFC 4646, or whether a Java-style
              locale (character ``_`` instead of ``-``) is accepted.
  
  
          @return: an instance ``Locale``.
