When manipulating sequences of bytes (as opposed to sequences of chars),
I find it is preferable to use unibyte strings.

Indeed, multibyte strings can work as well, but they can be more tricky
to work with since `aref' returns a "eight-bit byte" character rather
than a value between 128-255.

Of course, if your string can contain a mix of bytes and chars, you
don't have a choice.
