How to use strconv.QuoteRune() Function in Golang?

Go language provides inbuilt support to implement conversions to and from string representations of basic data types by strconv Package. This package provides a QuoteRune() function which is used to find a single-quoted Go string literal representing rune and the returned string uses Go escape sequences (\t, \n, \xFF, \u0100) to control characters and non-printable characters defined by IsPrint. To access QuoteRune() function you need to import strconv Package in your program.

Syntax:

func QuoteRune(rn rune) string

Parameter: This function takes one parameter of rune type, i.e., rn.

Return value: This function returns a single-quoted Go string literal which represents rune.

Example 1:

// Golang program to illustrate 
// strconv.QuoteRune() Function
package main

import (
    "fmt"
    "strconv"
)

func main() { 

    // Finding a single-quoted Go 
    // string literal representing rune
    // Using QuoteRune() function
    r := strconv.QuoteRune('♥')
    fmt.Println(r)

}

Output:

'♥'

Example 2:

// Golang program to illustrate
// strconv.QuoteRune() Function
package main

import (
    "fmt"
    "strconv"
)

func main() {

    // Finding a single-quoted Go 
    // string literal representing rune
    // Using QuoteRune() function
    val1 := strconv.QuoteRune('♣')
    fmt.Println("Result 1: ", val1)
    fmt.Println("Length 1: ", len(val1))

    val2 := strconv.QuoteRune('→')
    fmt.Println("Result 2: ", val2)
    fmt.Println("Length 2: ", len(val2))

}

Output:

Result 1:  '♣'
Length 1:  5
Result 2:  '→'
Length 2:  5
