If you want to read your strings in the source code, then you need
to edit them in the same codepage as you execute them in.  But for
code portability, do something like this:

{$ifdef DOS_CHARS}
  eacute = #$82;
  a-umlaut = #$84;
{$else} (* Windows characters *)
  eacute = #$E9;
  a-umlaut = #$E4;

It depends on how you print.  If you print from a Windows app (e.g.
Notepad), then yes, the characters must be in ISO-8859-1.  But if you
pipe your program output directly to PRN (the printer device) then use
your printer's native character set (consult the printer manual).
