get struct string in log file

Question

I have a script to print the same log like:

type Country stuct{
  cityName string
}

var c Country

and I

var logger = logrus.New()
logger.Debug(c)

but in the log file, it looks like:

country_name:\"\\347\\276\\216\\345\\233\\275\"

I want to know what \\347\\276\\216\\345\\233\\275\ means and how to read the true meanwhile my script read the log file.

What is logger in the posted code? The string "\347\276\216\345\233\275\" contains the octal escapes for "美国". — user5728991

The default logrus formatter writes JSON with ASCII encoding. You need to implement your own formatter and use UTF-8. See Logger.SetFormatter.

As I looked into the source code I didn't see any setting that can be set to change the encoding.

func convertOctonaryUtf8(in string) string {
    s := []byte(in)
    reg := regexp.MustCompile(`\\[0-7]{3}`)

    out := reg.ReplaceAllFunc(s,
        func(b []byte) []byte {
            i, _ := strconv.ParseInt(string(b[1:]), 8, 0)
            return []byte{byte(i)}
        })
    return string(out)
}

the func get the "\347\276\216\345\233\275\" mean
