package main

import (
    "fmt"
    "strconv"
    //"unicode/utf8"
)

func main() {
    rs := []rune("golang中文unicode编码")
    json := ""
    for _, r := range rs {
        rint := int(r)
        if rint < 128 {
            json += string(r)
        } else {
            json += "\\u"+strconv.FormatInt(int64(rint), 16) // json
        }
    }
    fmt.Printf("JSON: %s\n", json)

    r, _ := strconv.Unquote(`"` + json + `"`)

    fmt.Printf(r)


    //fmt.Printf(string(json))
}
