strconv.IsGraphic()

The IsGraphic() function is an inbuilt function of the strconv package which is used to check whether the given rune is defined as a Graphic by Unicode. Graphic characters include letters, marks, numbers, punctuation, symbols, and spaces, from categories L, M, N, P, S, and Zs.

• Category L: The set of Unicode letters
• Category M: The set of Unicode mark characters
• Category N: The set of Unicode number characters
• Category P: The set of Unicode punctuation characters
• Category S: The set of Unicode symbol characters
• Category Zs: The set of Unicode characters (Separator, space)

It accepts a parameter (rune) and returns true if the given rune is defined as a Graphic by Unicode; false, otherwise.

Syntax:

func IsGraphic(r rune) bool

Parameter(s):

• r : The rune value which is to be checked.

Return Value:

The return type of the IsGraphic() function is a bool, it returns true if the given rune is defined as a Graphic by Unicode; false, otherwise.

Example 1:

// Golang program to demonstrate the
// example of strconv.IsGraphic() Function

package main

import (
	"fmt"
	"strconv"
)

func main() {
	fmt.Println(strconv.IsGraphic('x'))
	fmt.Println(strconv.IsGraphic(' '))
	fmt.Println(strconv.IsGraphic('!'))
	fmt.Println(strconv.IsGraphic('☺'))
	fmt.Println(strconv.IsGraphic('☘'))
	
	fmt.Println(strconv.IsGraphic('\n'))
	fmt.Println(strconv.IsGraphic('\007'))
}

Output:

true
true
true
true
true
false
false

Example 2:

// Golang program to demonstrate the
// example of strconv.IsGraphic() Function

package main

import (
	"fmt"
	"strconv"
)

func main() {
	var x rune
	var result bool

	x = '☺'
	result = strconv.IsGraphic(x)
	fmt.Printf("%T, %c\n", x, x)
	fmt.Printf("%T, %v\n", result, result)

	x = '\u2665'
	result = strconv.IsGraphic(x)
	fmt.Printf("%T, %c\n", x, x)
	fmt.Printf("%T, %v\n", result, result)
}

Output:

int32, ☺
bool, true
int32, ♥
bool, true
