Why all Chinese Characters on the PDF report displayed as rectangular box in HRPro Web Client/EPortal?
When a PDF report contains Chinese characters, Chinese characters are displayed as rectangular boxes.
The web server did not have the Arial Unicode MS font that the report components required to render the Chinese characters.
You can either
Install the Arial Unicode MS font to the Server by right click the ARIALUNI.TTF true type font (inside the fonts sub folder in the WebClient or EPortal Web Site folder) using Windows Explorer. Right-Click and select install for all users. And then reboot the server.
