Encoding.Convert Unicode 到代码页 864

Question

我正在尝试使用 C# 中的 Encoding.Convert 方法，使用以下代码将字符串从编码 1256 转换为 864（均为阿拉伯语）。

    static void example()
    {
        string unicodeString = "ابتثجحخدذرزسشصضطظعغفقكلمنهوي";
        // Create two different encodings.
        Encoding cp1256 = Encoding.GetEncoding(1256);
        Encoding unicode = Encoding.Unicode;

        // Convert the string into a byte array. 
        byte[] unicodeBytes = unicode.GetBytes(unicodeString);

        // Perform the conversion from one encoding to the other. 
        byte[] cp1256Bytes = Encoding.Convert(unicode, cp1256, unicodeBytes);
        //                              ^
        //                              |
        //                           Above convert works

        Encoding cp864 = Encoding.GetEncoding(864);
        byte[] cp864bytes = Encoding.Convert(cp1256, cp864, cp1256Bytes);
        //Above convert does not work and it returns an array of ?

        string cp864String = cp864.GetString(cp864bytes);

        // Display the strings created before and after the conversion.
        Console.WriteLine("Original string: {0}", unicodeString);
        Console.WriteLine("CP864 converted string: {0}", cp864String);

    }

从 UNICODE 到 1256 的转换工作正常，我得到了所有字符，但是，当我从 1256 转换到 864 时，我得到了问号字符 (?)。

有什么建议吗

Maybe Encoding.GetEncoding(864).GetBytes is not supported by Operating System. But you can implement your own conversion from characters to bytes using this table:
