Indy UDP Server: how to send/receive a non-english string? was created by Roman

I am using TIdUDPserver to send and receive strings. The transmission and reception of strings is carried out on one computer in different applications.

Sending I do this:

procedure TForm1.Broadcast(Msg : String; Param : string);
begin
  if Param <> '' then
    Msg += ':' + Param;
  if UDP.Active then
    UDP.Broadcast(Msg, 9999);
end;

UDP is TIdUDPserver component.

Reception I do this:

procedure TForm1.UDPUDPRead(AThread : TIdUDPListenerThread; const AData : TIdBytes; ABinding : TIdSocketHandle);
begin
  case ABinding.Port of
    9999:
      Label1.Caption := BytesToString(aData);
  end;
end;

Everything works as long as I use English text. If I send Russian text, I receive garbage:
Sent 'Hello!' --- Received 'Hello!'
Sent 'Привет' --- Received '??????'

I don't understand where, when and how does Indy recode the strings? What should be done to transmit / receive strings without problems?
