Golang unicode.IsSpace() function usage example. Useful when you want to determine if an input character/rune is a space.
package main
import (
"fmt"
"unicode"
)
func main() {
space := unicode.IsSpace(' ')
fmt.Println(" is a space ? : ", space)
digit := unicode.IsSpace('1')
fmt.Println("1 is a space ? : ", digit)
tab := unicode.IsSpace('\t')
fmt.Println("Tab is a space ? : ", tab)
newLine := unicode.IsSpace('\n')
fmt.Println("New line is a space ? : ", newLine)
}
Output :
is a space ? : true
1 is a space ? : false
Tab is a space ? : true
New line is a space ? : true
