package main

func main() {
    text := "This is a very long text. OK, maybe it is not that long after all."
    counter := make(map[string]int)
    for _, c := range text {
        //fmt.Printf("%v", string(c))
        if string(c) != " " {
            counter[string(c)]++
        }

    fmt.Println(text)
    for char, count := range counter {
        fmt.Printf("%v: %v\n", char, count)
