PPTX to PDF - Frutiger font issue with bold property

Aspose.Slides Product Family

When I create a PPTX presentation and try to save it to PDF, bold texts, which are using Frutiger fonts (Frutiger 45 Light or Frutiger 55 Roman) are export incorrectly. They are neither bold nor normal - please see attached files.
I was testing with latest Aspose.Slides.NET - 19.5.0. This was working fine in old versions (for example: 16.7)

Could you tell me if there is a quick solution to this problem?

Attached you can also find sample project.

Thanks for sharing requested information with us.

The issues you have found earlier (filed as SLIDESNET-41227) have been fixed in this update.

Just to say, we’ve found that this issue was fixed up until v20.7.0.
But with the latest version, v21.4.0, it’s broken again.

@ipeadmin,
Our development team investigated the issue. “Frutiger 45 Light” and “Frutiger 55 Roman” fonts have a style by default (Italic and Bold), therefore any PDF editors can not use a style parameter for the same fonts. For example, “Frutiger 45 Light” font has an Italic style by default and it can not have a Bold style in the saved PDF file. If you save the presentation to a PDF file via PowerPoint, you will have the same result. The saved PDF file will not have the Bold style for the “Frutiger 45 Light” font.
