uPerform server View as end user Display Chinese Font Error

Hello everyone!

A question about server configuration.

In uPerform client, after editing, the file can be published in Chinese.

However, when upload to uPerform server, and view as end user, the pdf file cannot display Chinese font. The English font can be displayed.

p.s.1 The question only occurs for Pdf, other files such as html, word and ppt are fine.

p.s.2 The uPerform server has already installed Chinese font for Pdf.

How to configure the uPerform server to display a specific font ?

Thanks and Regards.
