Hi Prem,


We appreciate your cooperation.
We investigated this issue at our end and reproduced successfully using older version of the API that is 3.2.2. However, if you integrate latest version of the API that is 3.7.0 in your application/project, you will not face same issues. Hence, we’d recommend you to utilize latest version of the API in your application/project.
Please find the attached screenshots of viewer output.

Kind regards

Hi Atir,


Many thanks for update.

We updated with latest version of API 3.7.0, with this issue 1 resolved, issue 2 still exists (unable to render special characters in viewer).

Please find attached document and let me know for any questions.

Hi Prem,


You are welcome.
issue 2 still exists (unable to render special characters in viewer).
We are not facing this issue at our end. Please find the attached output screenshot.
Moreover, we’d recommend you to clear cache and delete temp files of this particular document created in temp folder (GroupDocs.Viewer-for-Java\Showcase\GroupDocs.Viewer-for-Java-using-JSP\storage<b>temp).
Hope it’ll resolve your issue.

Kind regards

Hi Atir,


Please go through the attached zip file, which contains our pom.xml (using the same dependency - 3.7.0).

Hi Atir,


I have setup the project with 3.7.0 version, still I am facing the same problem - viewer unable to recognize the special characters.

My local setup is as following:
windows 7
maven
java 8

Are any fonts required for it? or we missing anything?

Please advise.

Hi Prem,


We investigated the issues using the provided project. We’re still not able to reproduce it at our end. We are using Jetty Server to run the program/application. Hence, just un-commented the tag in pom.xml file of the provided project.

Kind regards

Hi Atir,


Thanks. Yes ran it using jetty plugin, its rendered without any issues in jetty server.

We will be using groupdocs in different application servers (tomcat in dev, weblogic in uat/prod environments). You can recreate this issue in using tomcat 8.x or 9.x (special characters are not rendered as expected).

Please go through this issue.

Thanks,
Prem Kumar
