[Lazarus] File encoding changing silently

[Gabor Boros]

Under test case creation indentified the Append problem.
I used Edit; after Append; and when removed the Edit; the record 
inserted properly to the  DataSet. Below example works.
But if put the MemDataset to the form set name to DSet add a field with 
the object inspector set name to NAME, set type to ftString and size to 
20. Remove the first 2 lines after begin (.Create and .FieldDefs.Addd) 
the result (dset.txt) contains only the header. With dynamic creation 
the file contains the 2 records.

procedure DSet_Test;
var
   DSet:TMemDataset;

begin
   DSet:=TMemDataset.Create(Self);
   DSet.FieldDefs.Add('NAME',ftString,20);
   DSet.CreateTable;
   DSet.Open;

   DSet.Append;
   DSet.FieldByName('NAME').Value:='aaa';
   DSet.Post;

   DSet.Append;
   DSet.FieldByName('NAME').Value:='bbb';
   DSet.Post;

   DSet.SaveToFile('c:\dset.txt');

   DSet.Close;
end;
