符文类型说明

Question

I have found rune type in Go and have a simple question but worth an explnation.

I fount that it is an alias for int32 and purpose is to distinguish number and character values.

http://golang.org/pkg/builtin/#rune

But I am confused with the term "rune" what actually it stands for ? e.g uint == unsigned int

Rune stands for letter. ("Runes" are the letters in a set of related alphabets known as runic alphabets, which were used to write various Germanic languages before the adoption of the Latin alphabet. [Wikipedia]).

If a variable has type rune in Go you know it is intended to hold a unicode code point. (rune is shorter and clearer than codepoint). But it is technical a int32, i.e. its representation in memory is that of an int32.
