Returns the current proxy class.

# File activesupport/lib/active_support/multibyte.rb, line 17
def self.proxy_class
  @proxy_class ||= ActiveSupport::Multibyte::Chars
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

# File activesupport/lib/active_support/multibyte.rb, line 12
def self.proxy_class=(klass)
  @proxy_class = klass
end
