Lack of documentation for encoding fallbacks

[ulrj]

Description

Hi

neither me not copilot found any documentation why the following program (in particular the GetBytes part) does what it does and if there are other character replacements. I think there should be a full table of character replacements applied somewhere documented or easily retrievable in code.

using System;
using System.Text;

namespace EncodingFun1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine(Encoding.Latin1.GetString(Encoding.Latin1.GetBytes("© Š š Ž ž Œ œ Ÿ €")));
            Console.ReadKey();
        }
    }
}

Copilot asked me to report this here. So I did.

Best Regards

Marc
