unicode.IsGraphic()

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

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

Return Value:

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

Example 1:

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

package main

import (
	"fmt"
	"unicode"
)

func main() {
	fmt.Println("unicode.IsGraphic('9'):",
		unicode.IsGraphic('9'))
	fmt.Println("unicode.IsGraphic('0'):",
		unicode.IsGraphic('0'))
	fmt.Println("unicode.IsGraphic('3'):",
		unicode.IsGraphic('3'))
	fmt.Println("unicode.IsGraphic('&'):",
		unicode.IsGraphic('&'))
	fmt.Println("unicode.IsGraphic('☺')",
		unicode.IsGraphic('☺'))
	fmt.Println("unicode.IsGraphic('🙈'):",
		unicode.IsGraphic('🙈'))
	fmt.Println("unicode.IsGraphic('!'):",
		unicode.IsGraphic('!'))
}

Output:

unicode.IsGraphic('9'): true
unicode.IsGraphic('0'): true
unicode.IsGraphic('3'): true
unicode.IsGraphic('&'): true
unicode.IsGraphic('☺') true
unicode.IsGraphic('🙈'): true
unicode.IsGraphic('!'): true

Example 2:

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

package main

import (
	"fmt"
	"unicode"
)

func main() {
	var r rune
	var result bool

	r = '🙈'
	result = unicode.IsGraphic(r)
	if result == true {
		fmt.Printf("%c is a Graphic by Unicode.\n", r)
	} else {
		fmt.Printf("%c is not a Graphic by Unicode.\n", r)
	}

	r = '\t'
	result = unicode.IsGraphic(r)
	if result == true {
		fmt.Printf("%c is a Graphic by Unicode.\n", r)
	} else {
		fmt.Printf("%c is not a Graphic by Unicode.\n", r)
	}

	r = 'Ɐ'
	result = unicode.IsGraphic(r)
	if result == true {
		fmt.Printf("%c is a Graphic by Unicode.\n", r)
	} else {
		fmt.Printf("%c is not a Graphic by Unicode.\n", r)
	}
}

Output:

🙈 is a Graphic by Unicode.
	 is not a Graphic by Unicode.
Ɐ is a Graphic by Unicode.
