View a PDF file with Chinese font using document viewer API in .NET

Hello,I’m here to ask again.
I‘m using GroupDocs.Viewer 17.2.0 for .Net
When I view a pdf,I have a problem.
The source file is like thiszy.pdf (3.6 KB),but the view result is LM08TUHH(H7%J$KO`YQGV]8.png (51.5 KB)
Is there a solution to this problem?
Thank you very much!
