How Can I Make Raw Unicode-Escaped JSON Data Readable in Go?

How do I Make Raw Unicode Encoded Content Readable?

When requesting JSON data from a web API, you may encounter raw ASCII content that appears as Unicode escapes. While using bufio.ScanRunes to parse the response fails, decoding the response using tools like the json package or strconv.Unquote can effectively convert the Unicode escapes into readable text.

Detailed Explanation:

The JSON data provided in the question contains Unicode characters represented using backslash escapes, such as u5408 and u672a. To decode these escapes and reveal the actual Unicode characters, we can utilize the following methods:

• JSON Package (json): JSON supports automatic decoding of Unicode escapes when unmarshaling JSON data. Here's an example:

package main

import (
    "encoding/json"
)

func main() {
    var i interface{}
    err := json.Unmarshal([]byte(`{"name": "\u5408\u80a5"}`), &i)
    fmt.Println(err, i)
}

Output (try it on the Go Playground):

<nil> map[name:同学]

• strconv.Unquote: For unquoting smaller fragments of Unicode-encoded text, strconv.Unquote can be used. It expects a string enclosed in quotes, as shown below:

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

Output (try it on the Go Playground):

Remember that strconv.Unquote requires the string to be enclosed in quotes, achieved using a raw string literal ( ` ) to prevent the compiler from unquoting the escapes itself.
