A note for myself

When you need to do something with strings length, consider using unicode/utf8 package. len() function doesn’t work good for special character containing strings. For example les accents in French or modified letters in Turkish alphabet.

package main

import (
	"fmt"
)

func main() {
	fmt.Println(len("Sadıç")) // will print 7
	fmt.Println(len("Adélaïde")) // will print 10
}

You should use unicode/utf8 package to measure length of unicode strings.

package main

import (
	"fmt"
	"unicode/utf8"
)

func main() {
	fmt.Println(utf8.RuneCountInString("Sadıç")) // 5
	fmt.Println(utf8.RuneCountInString("Adélaïde")) // 8

}
