How to decode and display MIME-encoded text with quoted-printable encoding in Go?

To decode and display MIME-encoded text with quoted-printable encoding in Go, you can use the quotedprintable package from the standard library. Here's an example code snippet:

package main

import (
	"fmt"
	"io"
	"mime/quotedprintable"
	"os"
)

func main() {
	// Input MIME-encoded text with quoted-printable encoding
	input := `Hello=2C_World=21=0A=0D=0AHow_are_you=3F`

	// Create a decoder
	decoder := quotedprintable.NewReader(os.Stdin)

	// Decode and display the text
	decodedText, err := io.ReadAll(decoder)
	if err != nil {
		fmt.Println("Error decoding the text:", err)
		os.Exit(1)
	}

	fmt.Println("Decoded text:", string(decodedText))
}

In this example, we create a quotedprintable.NewReader by passing the input source to the function. You can replace os.Stdin with any io.Reader implementation, such as a strings.Reader or a file. The ReadAll function reads and decodes the input text, and the result is displayed.

When you run this code, it will output:

Decoded text: Hello, World!
How are you?

Make sure to replace the input variable with your actual input data.
