How to convert a rune to unicode-style-string like `\u554a` in Golang?

Question

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

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

Answer 1

package main

import "fmt"
import "strconv"

func main() {
    quoted := strconv.QuoteRuneToASCII('啊') // quoted = "'\u554a'"
    unquoted := quoted[1:len(quoted)-1]      // unquoted = "\u554a"
    fmt.Println(unquoted)
}

This outputs:

\u554a
