What's the need of rune as a separate type?

Why there is need of rune i.e. Unicode strings as a separate type from string i.e. ASCII strings? Couldn't it just both type of strings have one type i.e. string like how languages have it?

Two things;

A rune represents a single Unicode Code Point (UTF-32 encoded, I assume).

A string represents a sequence of Unicode Code Points, UTF-8 encoded (in Go).
