I believe pchar has special treatment where pchar[i] is the same as pchar^[i]

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 begin buffer[I] := Byte(Hello[I]); <---- Works just fine. end; I fail to understand why. What I'm missing?
