But that changes the encoding of 'data' as a side-effect. To prevent that,
you'd need

  data.dup.force_encoding("ASCII-8BIT")[1,3].bytes.to_a

which is getting a bit messy. OTOH, I'm not sure how often you'd want to
handle a string which has been tagged as UTF-8 in this way.

BTW, "BINARY" is a synonym for "ASCII-8BIT" and probably makes more sense
here. But oddly, you can't use a Symbol.

irb(main):036:0> data.force_encoding("binary")
=> "\xC3\xA9\xC3\xA9"
irb(main):037:0> data.encoding
=> #<Encoding:ASCII-8BIT>
irb(main):038:0> data.force_encoding(:binary)
