Hello everybody.
I wanna  trying to understanding, how need to read the text file with
any type of BOM and automatically convert it to UTF8 or Wide chars. 

I am used in Delphi the TStreamReader  like this snippet and can read
any char :

  FS := TFileStream.Create(FileName, fmOpenRead + fmShareDenyNone);
  try
    FSR := TStreamReader.Create(FS, TMBCSEncoding.Create(CP_UTF8, 0,
0));
    try
      FS.Seek(0, 0);
      while not FSR.EndOfStream do
        parseBuff;
    finally
      FSR.Close;
      FSR.Free;
    end;
  finally
    FS.Free;
  end;



... but in te Lazarus the TStreamReader haven't the constructor with
input parameter as instance of TEncoder.

Thank you for any answer.
