c# - 无法将文本从一种编码解码为另一种编码

Question

我从 html 网站上读取了一些文本，需要存储数据。我从网站上知道源编码 (iso-8859-1) 和目标编码 (windows-874) http://alexpad.com/textdecoder

源文本是“áÁèãÔÁ”，我需要将其转换为“แม่ริม”但是输出总是“??????”这是 [63,63,63,63,63,63] 的数组

string text = "áÁèÃÔÁ";
Encoding fromEncoding = Encoding.GetEncoding("iso-8859-1");
Encoding toEncoding = Encoding.GetEncoding("windows-874");
byte[] fromBytes = fromEncoding.GetBytes(text);
byte[] toBytes = Encoding.Convert(fromEncoding, toEncoding, fromBytes);
string result = toEncoding.GetString(toBytes);

预期结果是“แม่ริม”实际结果是“??????”这是错误的

Answer 1

两种编码的区别是一个值160，那么是不是一小写一大写呢？

            string iso = "áÁèÃÔÁ";
            string[] isoBytes = iso.Select(x => ((byte)x).ToString()).ToArray();
            Console.WriteLine("Iso " + string.Join(",",isoBytes));

            string win = "แม่ริม";
            string[] winBytes = win.Select(x => ((byte)x).ToString()).ToArray();
            Console.WriteLine("Windows " + string.Join(",",winBytes));

            Console.ReadLine();
