extended ASCII and windows-1252 (different codes)

I have a string, which contains "ä" char. Default encoding I have is 1252. And the char code is 228. How can I convert it to extended ASCII in order to have this char with code 132?

You need to use encoding 437 (see https://en.wikipedia.org/wiki/Code_page_437). This will then correctly convert the extended ASCII symbol "ä" to the corresponding character in ANSI 1252:

using System;
using System.Text;

namespace helloworld
{
public class Program
{
    public static void Main(string[] args)
    {
         string text = "ä";

         byte[] bytes = Encoding.GetEncoding(1252).GetBytes(text);

         var convertedBytes = Encoding.Convert(Encoding.GetEncoding(1252),Encoding.GetEncoding(437), bytes);

         Console.WriteLine(Encoding.GetEncoding(437).GetString(convertedBytes));
    }
}

}

        var s = "ä";
        var extAscii = Encoding.GetEncoding ("437");
        var enc1252 = Encoding.GetEncoding (1252);
        var bytes = enc1252.GetBytes (s);
        Console.WriteLine (bytes[0]);
        var newBytes = Encoding.Convert (enc1252, extAscii, bytes);
        Console.WriteLine (newBytes[0]);

This code produces 228, 132. The Extended ASCII aka codepage 437 is pretty exotic these days.
