Cannot unmarshal struct when key is also ASCII escaped

[Andrew-M-C]

version: v1.1.10

code:

package main

import (
	"encoding/json"
	"fmt"
	
	jsoniter "github.com/json-iterator/go"
)

type obj struct {
	Msg string `json:"消息"`
}

func main() {
	jsonit := jsoniter.ConfigCompatibleWithStandardLibrary

	// \u6D88\u606F are escaped charecters for Chinese word "消息"
	b := []byte(`{"\u6D88\u606F":"\u6D88\u606F"}`) 

	
	o := obj{}
	json.Unmarshal(b, &o)
	fmt.Printf("got json object: %+v\n", o)

	o = obj{}
	jsonit.Unmarshal(b, &o)
	fmt.Printf("got jsonit object: %+v\n", o)
}

Go output:

got json object: {Msg:消息}
got jsonit object: {Msg:}

But expected:

got json object: {Msg:消息}
got jsonit object: {Msg:消息}

Similar issue exists on https://github.com/goccy/go-json/issues/234 go-json package as well

However, official "encoding/json" works well

This was addressed as well
