Go: Write carriage return with IO [duplicate]

Question

I'm trying to write on a file in Go with IO.WriteString, but even writing "\n" character it does not print the carriage return. I think maybe is not the carriage return itself what i need to write, in Windows, if i open the txt file with Wordpad, the carriage return is shown, but not in the notepad.

Any ideas about this behaviour?, here is the code:

//Write
t := time.Now().Local()
src, err := os.Stat("/dir")
if err != nil {
    log.Println(err, log.Llongfile)
}
if !src.IsDir() {
    err = errors.New("Folder does not exists")
    log.Println(err, log.Llongfile)
    err = os.MkdirAll("/dir", 665)
    log.Println(err, log.Llongfile)
}
f, err := os.Create("/dir" + "/File_" + t.Format("20060102") + ".txt")
n, err := io.WriteString(f, "Hello World\n")
n, err = io.WriteString(f, "Goodbye\n")

With this code, the result in the txt file is "Hello WorldGoodbye" if i open it in Windows notepad.

Thanks.

The problem was the way Windows expects carriage return, "\n" is Unix way, and "\r\n" is Windows way.

So, just replacing it does the trick.

n, err := io.WriteString(f, "Hello World\r\n")
