special character (i.e. ¬, ∧)is used.

Hi!
There are special characters in the PPTX file you provided, but Impress does not "see" those, so it will not implement it into a PDF file if you export this PPTX.
I assume that screenshot of those characters was made when you used another application, not Impress.

I could reproduce those missing characters in MS 2013, WPS, SM 2018 and OnlyOffice. WPS and SM only showed an image of the characteres , MS and OnlyOffice let me edit them. Those characters have the font "Cambria Math", the rest of the slide uses Calibri.

Those characters are actually equations inserted into a shape.
