We have logged this problem in our issue tracking system as PDFJAVA-41380. You will be notified via this forum thread once this issue is resolved.

We apologize for your inconvenience.


We are from Thomson Reuters and there is Paid support subscription tie up with ASPOSE, can you please look into options to expedite in fixing above issue.


It is to inform you that the issue which you are facing is actually not a bug in Aspose.PDF. So, we have closed this issue (PDFJAVA-41380) as ‘Not a Bug’.

The correct extraction of text is impossible for the document. Adobe Acrobat returns similar result.

Can you please share result of Adobe Acrobat and is there any way to handle via Aspose related exception instead of returning Junk chars as output ?


Please open the PDF file in Adobe Acrobat reader/writer and copy the content using Ctrl + A and Ctrl +C. You can paste the content in notepad to see the same result as shown in attached image.

Can you check and confirm on other question related to handling of ASPOSE related exception for this kind of scenarios ?


Unfortunately, there is no API to throw exception for this case. In this case, Aspose.PDF mimics the Adobe.
