How to use strconv.QuoteRuneToGraphic() 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 QuoteRuneToGraphic() function which is used to find a single-quoted Go character literal representing the rune. If the rune is not a Unicode graphic character as defined by IsGraphic, then the returned string will use a Go escape sequence (\t, \n, \xFF, \u0100). To access QuoteRuneToGraphic() function you need to import strconv Package in your program with the help of import keyword.

Syntax:

func QuoteRuneToGraphic(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.

Let us discuss this concept with the help of the given examples:

Example 1:

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

import (
    "fmt"
    "strconv"
)

func main() {

    // Finding a single-quoted Go
    // string literal representing rune
    // Using func QuoteRuneToGraphic() function
    str := strconv.QuoteRuneToGraphic('♥')
    fmt.Println (str)
    
}

Output:

'♥'

Example 2:

// Golang program to illustrate 
// strconv.QuoteRuneToGraphic() Function
package main
 
import (
    "fmt"
    "strconv"
)
 
func main() {

    // Finding a single-quoted Go 
    // string literal representing rune
    // Using QuoteRuneToGraphic() function
    val1 := strconv.QuoteRuneToGraphic('®')
    fmt.Println("Result 1: ", val1)
   
    val2 := strconv.QuoteRuneToGraphic('\u2666')
    fmt.Println("Result 2: ", val2)

     val3 := strconv.QuoteRuneToGraphic('\u000a')
    fmt.Println("Result 3: ", val3) 
}

Output:

Result 1:  '®'
Result 2:  '♦'
Result 3:  '\n'
