I did a quick test in Delphi:

program doti;

{$APPTYPE CONSOLE}

Var
   i: Integer; // lowercase dotted i in turkish

begin
   for İ :=0 to 10 do // uppercase dotted I in turkish
     writeln(i);
end.

Results in

[dcc32 Error] doti.dpr(9): E2003 Undeclared identifier: 'İ'

Same for German:

program doti;

{$APPTYPE CONSOLE}

Var
   ẞ: Integer;

begin
   for ß :=0 to 10 do
     writeln(ß);
end.

[dcc32 Error] doti.dpr(9): E2003 Undeclared identifier: 'ß'

So indeed, case-insensitivity is lost. Even in German.
