Unmarshal modifies input data

[jpcosal]

When input data contains strings with escaped characters (e.g. "/"), input byte array passed to gojay.Unmarshal is altered.

A sample code is given below

package main

import (
	"log"

	"github.com/francoispqt/gojay"
)

func main() {
	data := []byte(`"msn.com\/fr-fr"`)
	var s string
	if err := gojay.Unmarshal(data, &s); err != nil {
		log.Println(err)
	}
	log.Printf("buffer is: %s\n", string(data))
}

This outputs "msn.com/fr-fr"", while original buffer is "msn.com\/fr-fr".
This is a problem because we need to use the original buffer as is to do other processing.

I've encountered this problem, too. Input that contains escape characters is unescaped, and a quote is added to the end of the buffer for each escape character present in the input:

package main

import (
	"log"

	"github.com/francoispqt/gojay"
)

func main() {
	data := []byte(`"\/foo\/bar"`)
	var s string
	if err := gojay.Unmarshal(data, &s); err != nil {
		log.Println(err)
	}
	log.Printf("buffer is: %s\n", string(data))
}

Output:

→ go run main.go 
2020/04/02 08:07:57 buffer is: "/foo/bar"""
