[fpc-pascal] questions mark linux and windows

[Luis Fernando Del Aguila Mejía]

I wrote this program.

var c,d: char;
Begin
  c:=#$00B1;
  Writeln(byte(c));
  Writeln(c);

  d:=#$0080;
  Writeln(byte(d));
  Writeln(d);
End.

When I compile on Linux, the variable "c" stores the value #$B1, and the 
variable "d" stores the value #$80.
But when I compile the program in Windows, "c" storage #$B1, and "d" store 
#$3F.
In windows, puts a question mark for the range : #$0080 to #$009F.

My questions is :
Why put the second byte in Linux and Windows puts a question mark?

P.D. The source code is at Win-1252
Thanks.
