What is the expected output here (here's the current output)

20:21 < [Coke]> rakudo: say "\xFDD0"
20:21 <+p6eval> rakudo 38907e: OUTPUT«===SORRY!===␤Invalid character for UTF-8
                encoding␤␤»
20:22 < [Coke]> rakudo: say "\xFFFD"
20:22 <+p6eval> rakudo 38907e: OUTPUT«�␤»
20:22 < [Coke]> rakudo: say "\xFFFE"
20:22 <+p6eval> rakudo 38907e: OUTPUT«===SORRY!===␤Invalid character for UTF-8
                encoding␤␤»
