PDF library: non english languages support

Question

I am using the following demo but the application is unable to render russian text. Any input on what could be wrong? Does PDF library not support non-english languages? If it is not supported when can we expect support for the same?

Hi ajit, 
 
Thank you for contacting Syncfusion support. 
 
We have support for drawing the different text language in PDF document using our PDF library. To render the non english character, we have to use the proper custom fonts which should support all the characters. Please refer to the below link for more information.

Please refer the below code snippet to render the Russian text in a PDF document, 




//Create a new PDF document 
            PdfDocument document = new PdfDocument(); 
 
            //Add a page to the document. 
            PdfPage page = document.Pages.Add(); 
 
            //Create PDF graphics for the page. 
            PdfGraphics graphics = page.Graphics; 
 
            string path = @"E:\ArialUnicode\arial-unicode-ms.ttf"; 
 
            Stream fontStream = new FileStream(path, FileMode.Open, FileAccess.ReadWrite); 
 
            //Create a new PDF true type font. 
            PdfTrueTypeFont tFont = new PdfTrueTypeFont(fontStream, 12, PdfFontStyle.Regular); 
 
            //Draw the text 
            graphics.DrawString("Sample  Привет мир", tFont, PdfBrushes.Black, Syncfusion.Drawing.PointF.Empty); 
 
            FileStream file = new FileStream("../../../OutputRussian.pdf", FileMode.Create, FileAccess.Write); 
 
            //Save the PDF document  
            document.Save(file);

The same solution does not work for Hindi (and other Indian language) although it works (for hindi etc.) in .Net Framework WebForms but does not work in ASP.NET Core/.net6.0 web applications.
