After trying the trial version 19.1 understood that Aspose.Cells support right-to-left languages like Arabic that we want in exporting Excel to PDF except for Charts.
It means if you have Arabic texts in charts of your Excel file and export it to PDF, the Arabic texts do not exported correctly. Each character represents as upper case. For example if you have سلام in the chart, you will see س ل ا م.
Type of the chart does not matter.
Good to know that I tried MS Excel 2016 exporting an excel(That contains Arabic in sheets and charts) to PDF with SaveAs dialog. It works fine.
Is it possible to fix this problem? If yes, when?
Actually my company wants to buy this product and our projects deal with a lot of excel files contain charts.
