Saving PPTX Causes: "Array Index Out Of Bounds" because of U+200F Character


character is contained in a text: U+200F : RIGHT-TO-LEFT MARK [RLM]

Can you please check ALL CHARACTERS to avoid same error ?!

    var presentation = new Aspose.Slides.Presentation(stream, loadOptions);
        WriteLog("Saving PowerPoint: " + outPpt,;
        presentation.Save(outPpt, Aspose.Slides.Export.SaveFormat.Pptx);
