Hi all, I don't suggest seeing Javascript as a great example for Rust.
It uses UTF-16, but was created back when UTF-16 was UCS-2, so
two-code-unit codepoints are poorly supported in Javascript (e.g. you
can't use them in regex character classes).

If you put that into NFD instead of NFC you get a different answer.
$ node

("hï" and "hï"'s length also differ in UTF-8: 3 bytes for NFC, 4 for NFD.)
