String Runes

len counts bytes, while converting to []rune counts Unicode code points.

package main

import "fmt"

func main() {
	var text = 
	bytes := len(text)
	runes := len([]rune(text))

	fmt.Println("text=", text)
	fmt.Println("bytes=", bytes)
	fmt.Println("runes=", runes)
	fmt.Println("sameCount=", bytes == runes)
}

package main

import "fmt"

func main() {
	var text = 
	bytes := len(text)
	runes := len([]rune(text))

	fmt.Println("text=", text)
	fmt.Println("bytes=", bytes)
	fmt.Println("runes=", runes)
	fmt.Println("sameCount=", bytes == runes)
}

package main

import "fmt"

func main() {
	var text = 
	bytes := len(text)
	runes := len([]rune(text))

	fmt.Println("text=", text)
	fmt.Println("bytes=", bytes)
	fmt.Println("runes=", runes)
	fmt.Println("sameCount=", bytes == runes)
}

rune count Go strings store bytes, and runes let code count Unicode characters more directly.
