Embedding fonts

When exporting to PPT/PPTX can fonts be embedded into the PPT/PPTX file?

Ill ask my question differently.

When I export a report using the built-in Word or Excel renderers, my fonts are preserved, so if I have the font installed on my machine I can see the fonts.

However I find when exporting the same report to Aspose PPT/PPTX that my fonts are reset to Microsoft Sans Serif

I know the fonts are installed on the live server and on my local machine.
The server has been rebooted. Is there any thing else I need to do to see the correct fonts when I export to PPT/PPTX?
