Types ShortString, AnsiChar and AnsiString in Delphi Tokyo for Linux

In Delphi Tokyo for Linux, what are the equivalent types of:

• ShortString
• AnsiChar
• AnsiString

I send this block of code to show how these types work for Windows but for Linux not:

     program Project1;

{$APPTYPE CONSOLE}

{$R *.res}

uses
  System.SysUtils;

Var
  Ch1   : Char;
  SStr1 : String;
  AStr1 : String;
{$IFNDEF LINUX}
  Ch2   : AnsiChar;
  SStr2 : ShortString;
  AStr2 : AnsiString;
{$ENDIF}
  Ch3   : UTF8Char;
  SStr3 : String;
  AStr3 : UTF8String;
begin
  try
    { TODO -oUser -cConsole Main : Insert code here }
    Ch1:= 'A'; SStr1:='AaBbCcD'; AStr1:='1234567';
    WriteLn('"',Ch1,'"-"',SStr1,'"-"',AStr1,'"');
{$IFNDEF LINUX}
    Ch2:= 'A'; SStr2:='AaBbCcD'; AStr2:='1234567';
    WriteLn('"',Ch2,'"-"',SStr2,'"-"',AStr2,'"');
{$ELSE}
    WriteLn('En Delphi Linux no se cuenta con los tipos Ansichar, ShortString y AnsiString');
    WriteLn('Cuáles son los tipos equivalentes?');
{$ENDIF}
    Ch3:= 'A'; SStr3:='AaBbCcD'; AStr3:='1234567';
    WriteLn('"',Ch3,'"-"',SStr3,'"-"',AStr3,'"');
    ReadLn;
  except
    on E: Exception do
      Writeln(E.ClassName, ': ', E.Message);
  end;
end.
