You're right Andrew. Thanks for pointing that out.

In addition to that, there's an even better way to access runes in a string:

package main

func main() {
    testString := "Señor"
    for index, rune := range testString {
        fmt.Printf("rune '%c' at index  %d\n", rune, index)
Enter fullscreen mode Exit fullscreen mode

which gives:

rune 'S' at index  0
rune 'e' at index  1
rune 'ñ' at index  2
rune 'o' at index  4
rune 'r' at index  5
Enter fullscreen mode Exit fullscreen mode

Yeah, %c would format it as a char, so you can avoid casting it to a string like I did with my fmt.Println call.
