How to use strconv.QuoteToGraphic() 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 QuoteToGraphic() function which is used to find a double-quoted Go string literal representing str and the returned string leaves Unicode graphic characters defined by the IsGraphic, unchanged and uses Go escape sequences (\t, \n, \xFF, \u0100) for non-graphic characters. To access QuoteToGraphic() function you need to import strconv Package in your program with the help of import keyword.

Syntax:

func QuoteToGraphic(str string) string

Parameter: This function takes one parameter of string type, i.e., str.

Return value: This function returns a double-quoted Go string literal which represents str.

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

Example 1:

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

import (
    "fmt"
    "strconv"
)

func main() {

    // Finding a double-quoted Go 
    // string literal representing str
    // Using func QuoteToGraphic() function
    str := strconv.QuoteToGraphic("\u2665 Welcome w3wiki \u2665")
    fmt.Println (str)
    
}

Output:

"♥ Welcome w3wiki ♥"

Example 2:

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

    // Finding a double-quoted Go 
    // string literal representing rune
    // Using QuoteToGraphic() function
    val1 := strconv.QuoteToGraphic(`"I like Δ    "`)
    fmt.Println("Result 1: ", val1)
    fmt.Println("Length 1: ", len(val1))
   
    val2 := strconv.QuoteToGraphic("I love \u2666")
    fmt.Println("Result 2: ", val2)
    fmt.Println("Length 2: ", len(val2))
}

Output:

Result 1:  "\"I like Δ\t\""
Length 1:  17
Result 2:  "I love ♦"
Length 2:  12
