Given the following example:
func main() {
buf := new(bytes.Buffer)
enc := json.NewEncoder(buf)
toEncode := []string{"hello", "wörld"}
enc.Encode(toEncode)
fmt.Println(buf.String())
}
I would like to have the output presented with escaped Unicode characters:
["hello","w\u00f6rld"]
Rather than:
["hello","wörld"]
I have attempted to write a function to quote the Unicode characters using strconv.QuoteToASCII and feed the results to Encode() however that results in double escaping:
func quotedUnicode(data []string) []string {
for index, element := range data {
quotedUnicode := strconv.QuoteToASCII(element)
// get rid of additional quotes
quotedUnicode = strings.TrimSuffix(quotedUnicode, "\"")
quotedUnicode = strings.TrimPrefix(quotedUnicode, "\"")
data[index] = quotedUnicode
}
return data
}
["hello","w\\u00f6rld"]
How can I ensure that the output from json.Encode contains correctly escaped Unicode characters?
