Description Trejkaz 2017-02-17 00:03:22 UTC
For the following test program:

namespace test
	class MainClass
		public static void Main(string[] args)
			byte[] data = { 0x1B, 0x24, 0x42, 0x7B, 0x7D, 0x1B, 0x28, 0x42 };
			string str = System.Text.Encoding.GetEncoding(50220).GetString(data);

Running on .NET on Windows: https://dotnetfiddle.net/zDmDiG
It prints the single character result: 鄧

Running on Mono on macOS, I get apparently no output, but if I write it to a file instead, some junk character is present.
