As if you have a string like "\u2713\u2715".

See in playground https://play.golang.org/p/AxpnCzNEOfr

package main

import (
    "fmt"
    "unicode/utf8"
)

func main() {
    src := "\u2713\u2715"
    r, _ := utf8.DecodeRuneInString(src)
    fmt.Printf("the first rune of src is %v, code: %d",string(r), r)
}

// Output
// the first rune of src is ✓, code: 10003
