Hum... isn't possible to works with files like "Silvio Clécio.txt"? :(

I tested SynZIP (http://synopse.info/fossil/wiki?name=Downloads) in Delphi,
and it worked fine:

  with TZipWrite.Create('Silvio Clécio.txt.zip') do
  try
    AddDeflated('Silvio Clécio.txt', True, 9);
  finally
    Free;
  end;

But, is inviable to I port my backup program to Delphi now.
