Of course, if you have a set of all the valid characters

No, it is not:
t.pas

var
x: Double;
d: Integer;
begin
Val('e+', x, d);
Writeln(x, ' ', d);
end.

So both Delphi and FPC reject 'e+' as a floating-point value,
although with different error positions.
The latter is probably a compatibility bug in FPC's Val procedure.
