[fpc-pascal] Copying a Pchar to an array of bytes

I'm not too familiar with Pchar, and apparently I'm missing something.

I have a Pchar string which I must copy into an array of bytes.

Could someone explain me while a move doesn't work while an assignment 
byte by byte does?

Here's a snippet of the code:

buffer: array [0..1023] of byte;
Hello: PChar = 'Hello from server';
   len := strlen(Hello);
Move(Hello,buffer,len); <--- Garbage in buffer - doesn't work
   for I := 0 to Pred(len) do
     buffer[I] := Byte(Hello[I]);  <---- Works just fine.

I fail to understand why. What I'm missing?


Do not do to others as you would have them do to you.They might have different tastes.
