PPTX to PDF - Korean characters are not displayed

Hello
Currently, if you enter Korean into PPTX file in our system, PDF file conversion is not possible.
If you enter English and special symbols, the file will be converted normally.
Please check it.

local environment

  • JAVA 1.7
  • WebLogic
  • WINDOW 10
  • aspose-slides-21.2-jdk16. jar

@korsam,
Thank you for the issue description. Could you please share the PPTX file with Korean characters for investigating the problem? Also, please share your PDF output.

It is difficult to share because of our security.
You can save and test Korean after entering a few
characters in the PPTX file.
Please reply as soon as possible.
Thank you

@korsam,

I checked it and found no problems with Aspose.Slides 21.2. It seems some font is missing in your environment. Please check messages about font substitutions as below:

LoadOptions loadOptions = new LoadOptions();
loadOptions.setWarningCallback(new FontWarningHandler());

Presentation presentation = new Presentation(pptxPath, loadOptions);
presentation.save(pdfPath, SaveFormat.Pdf);

More details: Getting Warning Callbacks for Fonts Substitution

I Tested using the LoadOptions Class provided
I do not think it’s a font problem

if you write down Korean it will be the same
presentation.save()
The process stops here and Out Of Memory Exception occurs

@korsam,
I still cannot reproduce your problem test.png (87.6 KB).
