You can still do C:=S[i]. What you cannot do is

  P:=PChar(S);
  While (P^<>#0) do
   SomeByteSizedOperation;

if the string type has some multibyte values, obviously the code for
  C:=S[i];
will be rather cumbersome. But it will guarantee you the I-th character
from the string. Since C will be FlorianChar, it'll be at least an integer
(2 bytes encoding info, 2 bytes actual value)
