How to Handle Encoded Unicode Content in JSON Using Go?

How to Handle Encoded Unicode Content

When you encounter raw ASCII content in a JSON response, it may be encoded Unicode content. To view the unquoted text, you can utilize the json package.

func main() {
    var i interface{}
    err := json.Unmarshal([]byte(src), &i)
    fmt.Println(err, i)
}

const src = `{"forum":{"id":"3251718","name":"\u5408\u80a5\u5de5\u4e1a\u5927\u5b66\u5ba3\u57ce\u6821\u533a","first_class":"\u9ad8\u7b49\u9662\u6821","second_class":"\u5b89\u5fbd\u9662\u6821","is_like":"0","user_level":"1","level_id":"1","level_name":"\u7d20\u672a\u8c0b\u9762","cur_score":"0","levelup_score":"5","member_num":"80329","is_exists":"1","thread_num":"108762","post_num":"3445881","good_classify":[{"class_id":"0","class_name":"\u5168\u90e8"},{"class_id":"1","class_name":"\u516c\u544a\u7c7b"},{"class_id":"2","class_name":"\u5427\u53cb\u4e13\u533a"},{"class_id":"4","class_name":"\u6d3b\u52a8\u4e13\u533a"},{"class_id":"6","class_name":"\u793e\u56e2\u73ed\u7ea7"},{"class_id":"5","class_name":"\u8d44\u6e90\u5171\u4eab"},{"class_id":"8","class_name":"\u6e29\u99a8\u751f\u6d3b\u7c7b"},{"class_id":"7","class_name":"\u54a8\u8be2\u65b0\u95fb\u7c7b"},{"class_id":"3","class_name":"\u98ce\u91c7\u5c55\u793a\u533a"}]}}`

Output:

<nil> map[forum:map[levelup_score:5 is_exists:1 post_num:3445881 good_classify:[map[class_id:0 class_name:全部] map[class_id:1 class_name:公告类] map[class_id:2 class_name:吧友专区] map[class_id:4 class_name:活动专区] map[class_id:6 class_name:社团班级] map[class_id:5 class_name:资源共享] map[class_id:8 class_name:温馨生活类] map[class_name:咨询新闻类 class_id:7] map[class_id:3 class_name:风采展示区]] id:3251718 is_like:0 cur_score:0

If you prefer to unquote a specific fragment, use strconv.Unquote():

fmt.Println(strconv.Unquote(`"\u7d20\u672a\u8c0b"`))

Output:

素未谋 <nil>

Note that strconv.Unquote() requires a string in quotes. Raw string literals can be used to enclose such strings, preventing the compiler from interpreting Unicode escapes.
