def initialize(**opts)
  @internal_encoding = Encoding.find(opts[:internal_encoding]) if opts[:internal_encoding]

  if opts[:encoding].kind_of?(String)
    _ext, int = opts[:encoding].split(':', 2)
    @internal_encoding = Encoding.find(int) unless @internal_encoding || int.nil?
  end

end

#kind_of?(object) ⇒ Boolean

Implement kind_of? in order to pretend to be an IO object.

Returns:

  • (Boolean)
