**Which product are you using?**
PDF.js Express Viewer
**PDF.js Express Version**
**Detailed description of issue**
Please note that I am using PDF.js (v1.1.114) and the ViewerJS (Version 0.5.8). There is an issue with Arabic PDF when it is rendering in the Google chrome and Microsoft Edge Browser. However the same PDF is rendered correctly in the Mozilla Firefox. I have uploaded the screenshot of the rendered PDF in the Google Chrome with highlighted the invalid characters.
**Expected behavior**
I am not allowed to upload multiple screenshot so I didn’t uploaded the screenshot of the rendered PDF in the Mozilla Firefox, that are showing invalid in the Google Chrome shown in the **Detailed description of issue**.
**Does your issue happen with every document, or just one?**
Every Document

Somehow the pdf is rendering correctly in the Mozilla Firefox shown in the below screenshot with the same highlighted text which is not correctly rendering in the Google Chrome and Microsoft Edge browsers.
