def internal_encoding
  # Use a trick here - instead of using `default_internal` we will create
  # an empty string, and then get it's encoding instead. For example, this holds
  # true on 2.1+ on OSX:
  #
  #     Encoding.default_internal #=> nil
  #     ''.encoding #=> #<Encoding:UTF-8>
  Encoding.default_internal || ''.encoding
