    # The default normalization used for operations that require normalization. It can be set to any of the
    # normalizations in NORMALIZATION_FORMS.
    #
    # Example:
    #   ActiveSupport::Multibyte.default_normalization_form = :c
    mattr_accessor :default_normalization_form
    self.default_normalization_form = :kc

    # The proxy class returned when calling mb_chars. You can use this accessor to configure your own proxy
    # class so you can support other encodings. See the ActiveSupport::Multibyte::Chars implementation for
    # an example how to do this.
    #
    # Example:
    #   ActiveSupport::Multibyte.proxy_class = CharsForUTF32
