How to convert a string containing escape sequences to a valid JSON string using strconv in Golang?

To convert a string containing escape sequences to a valid JSON string using the strconv package in Golang, you can use the strconv.Unquote function. Here's an example:

package main

import (
	"encoding/json"
	"fmt"
	"strconv"
)

func main() {
	str := `"Hello\tWorld"`

	// Unquote the string to remove escape sequences
	unquotedStr, err := strconv.Unquote(str)
	if err != nil {
		fmt.Println("Error unquoting string:", err)
		return
	}

	// Convert the unquoted string to a valid JSON string
	jsonStr, err := json.Marshal(unquotedStr)
	if err != nil {
		fmt.Println("Error marshaling to JSON:", err)
		return
	}

	fmt.Println(string(jsonStr)) // Output: "Hello\tWorld"
}

In this example, the str variable contains the input string with escape sequences (\t for tab character). The strconv.Unquote function is used to remove the escape sequences and convert it to the unquoted string (Hello\tWorld). Then, the json.Marshal function is used to convert the unquoted string to a valid JSON string ("Hello\tWorld"). Finally, the result is printed to the console.
