How to use strconv.QuoteToGraphic() Function in Golang?
Last Updated :

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 GeeksforGeeks \u2665")
fmt.Println (str)
}
Output:
"♥ Welcome GeeksforGeeks ♥"
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
