try emailing it zipped with max. compression to support@mindfusion.eu

Better edit out your email address above or it will get spammed. We have received the font file and ours is exactly the same when compared in binary mode, so problem is not font itself. If you attach a test project of yours showing failed export for MingLiU + Unicode we could find something else in program's state leading to problems. Have you tried if using same font as in reports along with Unicode encoding fixes spreadsheet's export?

We think this build should fix export -
https://mindfusion.eu/_temp/pdf_font_name.zip

Problem was MingLiU.ttf also contains native Chinese names of the font (like 細明體) which WPF probably returns first on Chinese versions of Windows. PDF objects need to be encoded in ASCII so exporter would fail if font name is in Chinese on your side, but worked for us since we get 'MingLiU' first. Now it should always encode using Latin name of the font. You'll still need to export using the Unicode option.

With following code

                       var activeSheet = workbookView.ActiveWorksheet;
                       PdfExporter pdfExporter = new PdfExporter();
                       //pdfExporter.FontCachePath = @"C:\ZZReport\pdflib-fontrecords.xml";
                       pdfExporter.AutoDetectEncoding = false;
                       pdfExporter.DefaultEncoding = Encoding.Unicode;
                       pdfExporter.Export(activeSheet, dialog.FileName);


I recompile the code and use the new library you send me.

Thanks

The debug show following

en-US:MingLiU
zh-HK:細明體
zh-TW:細明體


and I add following code in my program

           private void Window_Loaded(object sender, RoutedEventArgs e)
           {
                 var drawing = VisualTreeHelper.GetDrawing(test);
                 foreach (var child in drawing.Children)
                 {
                       var group = child as DrawingGroup;
                       if (group != null)
                       {
                             foreach (var child2 in group.Children)
                             {
                                   var glyphRun = child2 as GlyphRunDrawing;
                                   if (glyphRun != null)
                                   {
                                         foreach (var kv in glyphRun.GlyphRun.GlyphTypeface.FamilyNames)
                                         {
                                               Debug.WriteLine(
                                                     string.Format("{0}:{1}", kv.Key, kv.Value));
                                         }
                                   }

                             }
                       }
                 }
           }


Thanks

Here is the result and code are

                       var activeSheet = workbookView.ActiveWorksheet;
                       PdfExporter pdfExporter = new PdfExporter();
                       //pdfExporter.FontCachePath = @"C:\ZZReport\pdflib-fontrecords.xml";
                       pdfExporter.AutoDetectEncoding = false;
                       pdfExporter.DefaultEncoding = Encoding.Unicode;
                       pdfExporter.Export(activeSheet, dialog.FileName);


Thanks

This is the current version.

Here is the log file.
