[Arrow-Li]

• Version:github.com/json-iterator/go v1.1.12

• A json like below be panic when unmarshal with BinaryAsStringExtension

{
    "F": "{\"abc\":\"123\"}"
}

• Test Code

package main

import (
	j "github.com/json-iterator/go"
	je "github.com/json-iterator/go/extra"
)

type D struct {
	F []byte `json:"F"`
}

func main() {
	a := "{\"F\":\"{\\\"abc\\\":\\\"123\\\"}\"}"

	j.RegisterExtension(&je.BinaryAsStringExtension{})

	b := new(D)

	j.Unmarshal([]byte(a), b)
}

According to the source code, all unsafe UTF-8 character will be hexed.

You can try with:

a := "{\"F\":\"{\\\\x22abc\\\\x22:\\\\x22123\\\\x22}\"}"

However, I think this extension could be just an example (my POV: it is not very production-ready)
