You may recall that we discussed how to change the colors in kpdf?
settings / configure / accessibility / change colors
What does kpdf do if you change these settings? i.e., you can force whatever
colors you want, so maybe invisible characters can also be made to show
themselves?
Just a thought ...

One more mystery:
I opened Voronoi in kpdf, still only formulas. Then I "Ctrl-P" that
file and "preview" "print" ....surprise, surprise, the preview
screen
showed text plus embedded formulas perfectly!!
AND the paper-printout of all! pages was also perfect.
The culprit clearly is hidden in kpdf.
Good find.
I just tested that I can mark parts of the pdf, copy the text, and pasting
gives the expected content. Somehow kpdf renders the text
invisible/transparent/white.
