May want to test UTF-8 encoded symbols that take up 3 or 4 bytes as well.
Example string that contains all of these (from
https://mathiasbynens.be/notes/javascript-unicode#poo-test):

    "Iñtërnâtiônàlizætiøn☃💩"

It's not necessarily guaranteed that there is any decoding from utf8 involved
--- but I guess it doesn't hurt to add a more thorough unicode test case. Done
and done!
