PPT characters are unexpectedly changed


I am using Aspose.Slides to set document properties on PPT files. The properties are set fine, however when the PPT is opened, the text inside has been changed. For example, bullets have been changed to special characters and bold text is now unbolded. I am using version

Please help.



Please provide example of the source presentation and you code.

I will email you the PPT file.

Here is the code I am running -

Aspose.Slides.License slidesLicense = new Aspose.Slides.License();


Presentation presentation = new Presentation(fileName);

presentation.Author = "Author Name";

presentation.Company = "Company Name";

presentation.Keywords = "third second first";

presentation.Title = "Title of PPT";


When the code runs, compare slides 5-9 on the new file with the original file and you will see the changes that have taken place.


I got the PPT, thank you.
We will investigate this problem and fix.

Any updates?

We are working on this problem but looks like there is something wrong with your presentation.
Are you sure this presentation was created in MS PowerPoint or OpenOffice?
If I’m not mistaken PowerPoint can’t add hundreds of garbage properties to slide objects
and especially table cells. By the way, most of them doesn’t follow ppt file standard at all.

Do you have some other presentations with similar problems?


The presentation I sent you was created in MS PowerPoint. I am going to email you another presentation that has it's characters changed by the Aspose.Slides component.


We will inform you as soon as updates will be available.
