如何在Golang中将符文转换为unicode样式的字符串，例如`\ u554a`？

Question

If you run fmt.Println("\u554a"), it shows '啊'.

But how to get unicode-style-string \u554a from a rune '啊' ?

Answer 1

IMHO, it should be better:

func RuneToAscii(r rune) string {
    if r < 128 {
        return string(r)
    } else {
        return "\\u" + strconv.FormatInt(int64(r), 16)
    }
}
