Thanks for your request. The problem might occur because Aspose.Words does not support RTL upon rendering/converting to PDF. Your request has been linked to the appropriate issue. You will be notified as soon as this feature is supported.
Thanks for your request. I cannot reproduce the problem on my side using the latest version of Aspose.Words 9.5.0. The output document looks exactly as the input document after open save with Aspose.Words. Which version of Aspose.Words do you use for testing?
Thank you for additional information. I have tried one more time using Aspose.Words (9.0.0) and I still cannot reproduce the problem on my side. Could you please attach the PDF document produced on your side?
Also please note, usually we always check with the latest version. There is no sense to check with old versions.
