This works in my test with default font.

void TestChinese(Diagram diagram)
{
    var node = diagram.Factory.CreateShapeNode(20, 20, 30, 30);
    node.Text = "� �题";
} 

Have you set some specific font as property of nodes or styles?

Try either setting the NoFontFallback flag in nodes' TextFormat.FormatFlags to zero, or explicitly setting Font to one that contains Unicode characters.

Hi,

Have you tried Unicode encoding as in post linked above?

What happens if you remove the encoding properties? They might not be needed after you fixed on-screen rendering.

diagram.Factory.CreateShapeNode(10, 10, 40, 40).Text = "地狱其他凝胶";
var pdfex = new PdfExporter();
pdfex.Export(diagram, @"D:\test.pdf"); 

With that I'm seeing Chinese text in both Firefox and Edge, while Adobe Reader asks to download a font pack. On what OS are you seeing missing fonts? I believe that's what the question marks indicate.

You might need fonts both on server side for PdfExporter to use and on client side for PDF readers. Does attached PDF render correctly for you? Please attach your PDFs generated with and without encoding overrides and I will check them on my system.

Hi,

PDF generated on our side with default AutoDetectEncoding = true value looks correct. Does attached file render Chinese glyphs for you?

var pdf = new MindFusion.Diagramming.Export.PdfExporter
{
    PageSize =
        (PageSize)
            Enum.Parse(typeof(PageSize), diagramSize, false),
    Margins = { Bottom = 2, Top = 2, Left = 2, Right = 2 },
    InvisibleItems = true,
    AutoScale = MindFusion.Diagramming.Export.AutoScale.FitToWidth,
	//DefaultEncoding = System.Text.Encoding.Unicode,
	AutoDetectEncoding = true
}; 

If AutoDetectEncoding = true generates a different PDF for you, please attach it and our developer will compare with ours to investigate what might be going wrong. From what we can tell, the PDFs from your temp folder were generated with auto-detect disabled.

Adobe's font pack page was working for me the other day, and the PDF shows on my side after installing from there; maybe try updating your PDF Reader version in case they've obsoleted some URL used by old ones.

As for Chrome, it might be falling back to fonts without glyphs if it can't find the actual ones from the PDF file. Try opening the PDF in notepad and look for /FontName PDF tags. It should render correctly when you have these fonts installed on client's OS.
