Hi Pandian,
Thanks for sharing the detail. Perhaps, you are using an older version of Aspose.Words; as with Aspose.Words v14.6.0, I am unable to reproduce this problem on my side. Steps to test this issue.
1) Open input document in MS Word and change the font of text to IDAutomationC128L.
2) Use following code example to convert Word document Pdf.
Document
doc = new Document(MyDir
-
“Input-SampleDocument.docx”);
doc.Save(MyDir
+ "Out.pdf");

I would suggest you please upgrade to the latest version of Aspose.Words i.e. v14.6.0
and let us know how it goes on your side. I hope, this will help. I
have attached the input/output documents with this post for your kind reference.
