How Can I Make Raw Unicode-Encoded JSON Data Readable?

Raw Unicode Encoding: A Guide to Making it Readable

Many web API responses contain JSON data that employs raw Unicode encoding. While this format can be challenging to decipher, it can be made readable with the right approach.

The Challenge:

When a web API returns such a response, displaying the body as text using methods like fmt.Println() results in unreadable ASCII content. Attempts to parse the content using bufio.ScanRunes also fail.

The Solution: Unicode Decoding

To decode the raw Unicode encoding and make the content readable, we recommend using a JSON decoder. The provided example code demonstrates how this can be achieved:

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

By unmarshaling the response body into an interface{}, the JSON decoder automatically converts the Unicode escapes into their respective characters.

Alternative Approach: Manual Decoding

If you prefer a more direct approach, you can decode specific fragments of the Unicode-encoded string manually using the strconv.Unquote() function:

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

Remember to enclose the Unicode-encoded string in double quotes when using strconv.Unquote(), and be sure to use raw string literals to prevent the compiler from interpreting the escapes.

Conclusion:

By employing the techniques outlined above, you can effectively decode raw Unicode-encoded content and make it readable. This opens up the possibility of further processing and analysis of the retrieved JSON data.
