I have a local int type, Duration, type Duration int and I’ve added a String method to it (wrapped?, I’m not sure the terminology):

func (d Duration) String() string {
    num := strconv.Itoa(int(d))
    if d == 1 {
        return num + " second"
    } else {
        return num + " seconds"
    }
}

This works as expected when passing a Duration into a print function:

fmt.Println("season: ", d)

but when I add it to a list of strings, I end up with the replacement string character

strings := []string
strings[i] = string(s)

I’m displaying the characters in a fyne GUI application. Maybe I need to tell the app which character encoding?
