Behaviour deviates from Node dotenv

I am using the following code to compare the difference in behaviour.

require('dotenv').config()

console.log(process.env.TEST_ENV)

package main

import (
	"fmt"
	"os"

	"github.com/joho/godotenv"
)

func main() {
	if err := godotenv.Load(); err != nil {
		fmt.Fprintln(os.Stderr, err)
	}
	fmt.Println(os.Getenv("TEST_ENV"))
}

1. Double quotes without escape

   复制

   TEST_ENV="test"test"

   Node dotenv worked but godotenv failed to even parse the env file.

   

2. Double quotes with escape

   复制

   TEST_ENV="test\"test"    

   Node dotenv parsed the value literally but gotdotenv used \ to escape the double quote.

   

3. Exclamation mark with escape

   复制

   TEST_ENV="test\!test"

   Node dotenv parsed the value literally but godotenv used \ to escape the exclamation mark.

   

   An additional point here is that both the libraries parses exclamation marks without escape as well.

   复制

   TEST_ENV="test!test"

   

   However godotenv escapes exclamation during marshalling.
