It's also the case that `char` in Rust is a 32-bit primitive. Though, `String` being UTF-8 is convenient until you need to do Unicode operations on actual chars... It is surely better than dealing with UTF-16 "surrogate pairs"[2] in most pre-UTF-8 tech where a `char` is 16-bits but can't fit all Unicode codepoints without another 16-bit `char`.
