Json to CSV parsing with raw Data

[sharath chandra]

The issue with Golang to retrieve raw data from Json / string variable

```

I have a Json sample message something similar with special characters 

func main() {
     msg := []byte(`{"key":"ABC\u001d\u263aDEF"}`)
     m := make(map[string]interface{})
      json.Unmarshal(msg,&m)
      ConvertToCsv(m)
}


func ConvertToCsv(m map[string]interface{}){
     buf := new(bytes.Buffer)
     for k,v := range m {
            buf.WriteString(fmt.Sprintf("%v:%v",k,v))
     }
    fmt.Println(buf.String())
 }

```

Output is similar to 

```golang

key:ABC☺DEF

```

I am expecting something similar to :

key:"ABC\\u001d\\u263aDEF"

Is this possible by any means ?

https://golang.org/pkg/strconv/#QuoteToASCII

QuoteToAscii converts non printable characters to \xd  , but i literally want the same value .

QuoteToAscii will not produce the json compatible string or will not escape string in true sense like 

Conversion of "abc\u001d" will be converted to "abc\x1d" which is not compatible with json string

If there is no built in cooked function ,

Can you please through some pointers how to implement on own , i am not able to figure it out ...

See https://github.com/golang/go/blob/ccd9784edf/src/encoding/json/encode.go#L1031 as an example.

Also, note that the language name is Go, not Golang.

maybe something like https://play.golang.org/p/z-Yp4bh7jto
