CHAR(151) is not working properly in pdf and image


I have created a workbook with using a text formula CHAR(151).
I have used the following code
Workbook book = new Workbook(excelpath);
book.Save(outputpdfPath, SaveFormat.Pdf)
Here in my excel file the cell D9 has the formula CHAR(151) and it is displaying well in excel but when I save the same excel file in PDF format it is displaying some different value some square box.
Also I have noticed one more thing if we generate image of that same excel the same CHAR(151) was showing as line till recently but in the new version it is showing as a big dot,the code used to generate image is
ImageOrPrintOptions options = new ImageOrPrintOptions();
options.IsImageFitToPage = true;
options.OnePagePerSheet = true;
options.TiffCompression = TiffCompression.CompressionLZW;
options.ImageFormat = ImageFormat.Emf;
options.PrintingPage = PrintingPageType.Default;
SheetRender sr = new SheetRender(sheet, options);
sr.ToImage(0, outputImgPath);
Can you please look into this?
Thanks and Regards

Hi Mukundan,

Thank you for using Aspose products.

I have evaluated your presented scenario while using the latest version of Aspose.Cells for .NET 7.7.0. I am afraid, the issue didn’t replicate on my end with the latest build. Attached are the output PDF and EMF files that show the value of CHAR(151) correctly. Please give the latest version a try on your end, and let us know if you find any difficulty.

Hi Babar

Have you checked the issue with the sample code provided by me?
Because when I use workbook.CalculateFormula() api call these issues are still replicating but when I comment this method call workbook.CalculateFormula() then it is working fine.
Can you please check and let me know why this is failing in this case?
Thanks and Regards
