Returns the current proxy class.

  @proxy_class = klass
end

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.

ActiveSupport::Multibyte.proxy_class = CharsForUTF32
