Underline is exported to pptx as strikethrough for some fonts

Hi, we are experiencing some issues while trying to convert pdf to pptx file using aspose.pdf library. Underline is exported to pptx as strikethrough for some fonts. Please find the pdf input attached. Also, below is the code snippet to replicate this behaviour.

bug_254230.pdf (46.5 KB)

In case some options need to be passed to avoid such outcome, please advise.

@Test
  void exportPPTX_underlineIsExportedToAsStrikethroughForSomeFonts () throws Exception {
    var pdfBytes = new ClassPathResource("bug_254230.pdf").getInputStream().readAllBytes();
    try (Document srcDoc = new Document(pdfBytes)) {
      ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
      srcDoc.save(outputStream, com.aspose.pdf.SaveFormat.Pptx);

      var out = outputStream.toByteArray();

      Files.write(Path.of("bug_254230.pptx"), out, StandardOpenOption.CREATE);
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
