ISO-8859-1

Encoding Example

import java.nio.charset.StandardCharsets;
import java.util.Arrays;

public class ExtendedAscii {
    public static void main(String [] args) {
        // Include the Euro sign, which is in Extended ASCII
        String text = "Hello, World! €";
        byte[] encodedBytes = text.getBytes(StandardCharsets.ISO_8859_1);
        String encodedString = new String(encodedBytes, StandardCharsets.ISO_8859_1);
        System.out.println("Input Text Bytes: " + Arrays.toString(encodedBytes));
        System.out.println("Encoded String: " + encodedString);
    }
}

Decoding Example

import java.nio.charset.StandardCharsets;

        String decodedString1 = new String(encodedBytes1, StandardCharsets.ISO_8859_1);
        System.out.println("Decoded String: " + decodedString1);

        byte[] encodedBytes2 = {72, 101, 108, 108, 111, 44, 32, 87, 111, 114, 108, 100, 33, 32, -128}; // Hello, World! €
        String decodedString2 = new String(encodedBytes2, StandardCharsets.ISO_8859_1);
        System.out.println("Decoded String: " + decodedString2);
    }
