Aspose Words To Pdf Missing Font Subgroup


i’am converting a docx to pdf with Aspose.Words. However the generated pdf embedded fonts differs from exporting the same docx from within MS Word.

When exporting it to pdf with MS Word Acrobat Reader Document Properties shows following subbed Fonts:

Arial MT Truetype Ansi
Arial MT Truetype (CID) Identity-H

While Aspose converted pdf has only

Arial MT Truetype Ansi

Is there a reason for not including the same subbed Fonts and how can i add it? I’am using MS Word 2016 and my sample Docx just contains “Hello World” in Arial.

We have tested the scenario and have managed to reproduce the same issue at our side. For the sake of correction, we have logged this problem in our issue tracking system as WORDSNET-18420. You will be notified via this forum thread once this issue is resolved.

We apologize for your inconvenience.


It is to inform you that the issue which you are facing is actually not a bug in Aspose.Words. So, we have closed this issue (WORDSNET-18420) as ‘Not a Bug’.

You are facing the expected behavior. Aspose.Words tries to use /WinAnsiEncoding when possible and uses /Identity-H encoding only when it is not possible to use /WinAnsiEncoding. It is not clear why MS Word uses /Identity-H encoding for the „Hello World“ text. Generally MS Word prefers to use /WinAnsiEncoding as well. The Aspose.Words PDF output is correct and there are no violations of PDF and PDF/A-1 specifications.
