[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)
