C# winApp ช่วยแปลงค่า string ให้หน่อยครับ

using System;
using Ude;

class Program
{
    static void Main()
    {
        string input = "áÁ¹ ÁÍàµÍÃìä«´ì ÍÒÃìÊÂÒÁ";

        CharsetDetector detector = new CharsetDetector();
        detector.Feed(System.Text.Encoding.Default.GetBytes(input));
        detector.DataEnd();

        if (detector.Charset != null)
        {
            byte[] detectedBytes = Encoding.GetEncoding(detector.Charset).GetBytes(input);
            byte[] utf8Bytes = Encoding.Convert(Encoding.GetEncoding(detector.Charset), Encoding.UTF8, detectedBytes);
            string unicodeString = Encoding.UTF8.GetString(utf8Bytes);

            Console.WriteLine($"Detected Encoding: {detector.Charset}");
            Console.WriteLine($"Output: {unicodeString}");
        }
        else
        {
            Console.WriteLine("Failed to detect encoding.");
        }
    }
}
