Convert from Presentation to Pdf doesn't show Unicode Icons

[Paul Abramov]

Hey,

so I am converting a PPTX to a PDF.
As a result the unicode symbols do not show up.
I made an example code and attached the two results.
How I am able to fix this?

IPresentation pptxDoc = Presentation.Create();
ISlide firstSlide = pptxDoc.Slides.Add(SlideLayoutType.Blank);
ITable table = firstSlide.Shapes.AddTable(2, 2, 100, 120, 300, 200);
table.Rows.First().Cells.First().TextBody.AddParagraph($"\u2B9C");
table.Rows.First().Cells.Last().TextBody.AddParagraph($"\u2B9E");
table.Rows.Last().Cells.First().TextBody.AddParagraph($"\u2B9C\u2B9C");
table.Rows.Last().Cells.Last().TextBody.AddParagraph($"\u2328");

pptxDoc.Save(fileName.Replace("pdf", "pptx"));

PdfDocument pdfDocument = PresentationToPdfConverter.Convert(pptxDoc);

pdfDocument.Save(fileName);

pdfDocument.Close(true);

pptxDoc.Close();

Hi Paul,

Thank you for your patience.

From our further analysis, we found that glyph for the specified characters “ ⮜ ⮞⌨ ” are not available in a default font “Calibri”. So only these characters are missed in a converted PDF document. To overcome this issue, kindly use “Segoe UI Symbol” font for the paragraph in your end. Please find the below code snippet, which works properly in our end. 

 

 

IPresentation pptxDoc = Presentation.Create(); 

ISlide firstSlide = pptxDoc.Slides.Add(SlideLayoutType.Blank); 

ITable table = firstSlide.Shapes.AddTable(2, 2, 100, 120, 300, 200); 

IParagraph paragraph = table.Rows.First().Cells.First().TextBody.AddParagraph($"\u2B9C"); 

//Set font name of the paragraph text part as "Segoe UI Symbol" 

paragraph.TextParts[0].Font.FontName = "Segoe UI Symbol"; 

paragraph = table.Rows.First().Cells.Last().TextBody.AddParagraph($"\u2B9E"); 

paragraph.TextParts[0].Font.FontName = "Segoe UI Symbol"; 

paragraph = table.Rows.Last().Cells.First().TextBody.AddParagraph($"\u2B9C\u2B9C"); 

paragraph.TextParts[0].Font.FontName = "Segoe UI Symbol"; 

paragraph = table.Rows.Last().Cells.Last().TextBody.AddParagraph($"\u2328"); 

paragraph.TextParts[0].Font.FontName = "Segoe UI Symbol"; 

PdfDocument pdfDocument = PresentationToPdfConverter.Convert(pptxDoc); 

pdfDocument.Save("Output.pdf"); 

pdfDocument.Close(true); 

pptxDoc.Close();

 

Please let us know if you need any further assistances in this.
