Description
The Encoding.UTF8.GetString throws an exception in nF where as in the .Net 8 it does not.
How to reproduce
public class Program
{
public static void Main()
{
Debug.WriteLine("Hello from nanoFramework!");
byte[] bytes = new byte[6] { 0x42, 0x41, 0x44, 0xff, 0xfe, 0xfd };
var st = Encoding.UTF8.GetString(bytes,0,6);
Console.WriteLine(st);
Thread.Sleep(Timeout.Infinite);
}
}
Expected behaviour
Do not throw an exception and invalid character should be replaced with U+FFFD (0xEF, 0xBF, 0xBD).
