Character and Symbol are not clear in pdf

Hi Team,

While converting the PPT document to pdf. We are facing issue with pdf. We can see symbol & character are not coming clear with 100 percentage resolution with pdf file.
I am attaching the ppt document, expected pdf document, and pdf document which had an issue. Also, please find the code snippet which we are using to convert the ppt to pdf.

String rightsWatchMark = (String) ppt.getDocumentProperties().get_Item("RightsWATCHMark");
String encodedRightsWatchMark = Base64.getEncoder().encodeToString(rightsWatchMark.getBytes());
com.aspose.pdf.Document pdfDocument = new com.aspose.pdf.Document(outputPdfFilePath);
DocumentInfo documentProperty = pdfDocument.getInfo();
documentProperty.set_Item("RightsWATCHMark", encodedRightsWatchMark);; (1.4 MB)
