When creating PDF documents containing "SimSun" font (SimSun.ttc) or "MingLiu" font (MingLiu.ttc), a very large file is generated and the font appears to be incorrectly embedded and cannot be displayed by Adobe Reader. The sample code below generates a file containing one common Chinese character.

Having tested several fonts with the sample code, fonts contained in ".ttc" files all generated large files with display problems. Other fonts were fine. This issue could be related to http://synopse.info/forum/viewtopic.php?id=1528.

Resulting file sizes in my test were:
Fonts with problem:
MingLiu: 16.2MB
SimSun: 7.6MB

Fonts without problem:
KaiTi: 55KB
Microsoft YaHei: 17KB

procedure CreatePDFDoc();
var
  PDFDoc: TPDFDocumentGDI;
begin
  PDFDoc := TPdfDocumentGDI.Create;
  try
    PDFDoc.NewDoc;
    PDFDoc.AddPage;
    PDFDoc.EmbeddedTTF := True;
    PDFDoc.VCLCanvas.Font.Name := 'SimSun';
    PDFDoc.VCLCanvas.TextOut(100,100,#22909);
    PDFDoc.SaveToFile('PDFDoc_' + PDFDoc.VCLCanvas.Font.Name + '.pdf');
  finally
    PDFDoc.Free;
  end;
end;

Thanks for any help that can be given.
