There's no such thing as a UTF-8 string. You have a list of bytes
(byte string) and you have a list of characters (unicode). UTF-8 is a
function that can convert bytes into characters (and the reverse). You
may recognize that the list of bytes was encoded using UTF-8 but the
computer does not unless you explicitly tell it to. Does that help
clear it up?
