)

func main() {
    input := "é"
    t, err := iconv.Translator("ASCII//TRANSLIT", "UTF-8", 'x')
    if err != nil {
        log.Fatalf("Coult not get charset translator from UTF-8 to ASCII. Got error: %s\n", err)
        return
    }
    fmt.Print(hex.Dump([]byte(input)))
    n, cdata, err := t.Translate([]byte(input), true)
    if err != nil {
        log.Fatalf("Could not translate string '%s' to ASCII. Got error: %s\n", input, err)
    }
    fmt.Print(hex.Dump(cdata))
    output := string(cdata)
    log.Printf("Translated %d characters from UTF-8 ('%s') to ASCII ('%s')\n", n, input, output)
