.msi package v3.6.2 can't render some pptx files contained Chinese characters correctly

Describe the bug

.msi package v3.6.2 can't render some pptx files contained Chinese characters correctly, all Chinese characters disappeared in the preview window. See screenshot.

The bug probably caused by default Syncfusion PDF converter settings not properly handle font infomation. New Syncfusion version provide parameters to embed fonts into target PDF, see official docs. Maybe it would work.

To Reproduce
Steps to reproduce the behavior:

1. Download then select DICOM.pptx;
2. Press spacebar;
3. All Chinese characters disappeared in the preview window.

Expected behavior
All characters display correctly.

Desktop (please complete the following information):

• OS Version: Windows 10 1803;
• QuickLook Version: .msi package v3.6.2;
• Plugin Version: OfficeViewer Plugin v2

Unfortunately, EmbedFonts does solve the problem. Maybe it is better to use #358 to solve this issue.

I know the reason. The PPTX uses "华文楷体" font, but you don't have this font installed on your PC. The real solution is font substitution: https://help.syncfusion.com/file-formats/presentation/presentation-to-pdf#font-substitution-for-unavailable-fonts

UPDATE: Tested but only partially works. Some characters are now displayed while other not.

I have "华文楷体" installed on my PC.

Indeed this font is bundled together in office 365.
