func main() {
    bs_UTF16LE, _, _ := transform.Bytes(unicode.UTF16(unicode.LittleEndian, unicode.IgnoreBOM).NewEncoder(), []byte("測試"))
    bs_UTF16BE, _, _ := transform.Bytes(unicode.UTF16(unicode.BigEndian, unicode.IgnoreBOM).NewEncoder(), []byte("測試"))
    bs_UTF8LE, _, _ := transform.Bytes(unicode.UTF16(unicode.LittleEndian, unicode.IgnoreBOM).NewDecoder(), bs_UTF16LE)

    fmt.Printf("%v\n%v\n%v\n%v\n", bs_UTF16LE, bs_UTF16BE, bs_UTF8LE, bs_UTF8BE)
