Likely, because I doubt FPC has routines, other than UTF-8 <-> UTF-16 
conversion, that need to bother with surrogate pairs. I.e. the following 
code is fully correct in an UTF-16 environment:

procedure upcase(var s:widestring);

var i:longint;

begin
   for i:=1 to length(s) do
    s[i]:=upcase(s[i]);
end;

...because all characters that need upper/lower casing are in the BMP. 
Likewise, all possible thousand separators are in the BMP, so you don't 
need to bother with that either.

This would be the same behaviour as with widestrings. RTL routines are 
dump, smarter ones should go in sysutils.
