As slice is more flexible than array therefore, its flexibility is determined in terms of its size. Just like an array, it has indexing value and length but its size is not fixed. When we declare a slice we do not specify the size of it.fmt.Printf("char: '%c', ok: %#v\n", char, ok) } A better solution in this case would be to use a for loop and utf8.DecodeRuneInString to iterate over the existing string to find the ith unicode character.
