Characters from PPTX are missing with certain font in .NET

GroupDocs.Viewer Product Family
1

Hi,

Using GroupDocs.Viewer from GroupDocs.Total.NetFramework package 25.7 does not convert all characters to HTML. To be more precise, the characters are there, as you can copy&paste them, but they are not displayed.
PPTX missing chars.zip (1.2 MB)

I’ve attached the “PPTX chars missing.pptx” and the “PPTX chars not missing.pptx” where the only difference is the used font. Here a screenshot comparing the outputs from GroupDocs:

I was using “HtmlViewOptions.ForEmbeddedResources” without any additional options.
Can you please take a look?
