That may be correct. It also may be that the stuff you are trying to turn into a String is not text at all. In fact, if that is a raw network packet that you have sniffed, it is pretty much guaranteed that some of the packet (the IP/ICMP packet headers) won't be text.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
