  # In Ruby 1.9+ we have encoding methods that can check the content of
  # the string, so use them to see if what we have is unicode. If so,
  # good! If not, then just treat is as binary.
  #
  # No such thing in Ruby 1.8. So there we need to use Iconv to try and
  # convert it to unicode. If it works, good! But if it raises an
  # exception then we'll treat it as binary.
