png showcasing the bug

In formulas within a pdf file, the capital sigma (U+03A0) and the capital pi
(U+03A3) are rendered as bullets (U+2022) respectively as division signs (U+00F7).
It's definitely a problem of the program itself, as the formulars are put out
correctly if shown with Adobe PDF Reader. I do not know if this bug occurs with all greek letters.

The pdf uses the Symbol font and does not embed it. Probably you are getting the wrong substitution for it. Read http://freedesktop.org/wiki/Software/poppler and make sure your fontconfig setup returns the "correct" Symbol font.

On the other hand blame whoever generated the pdf file for not embedding the font

Attaching another document showing this issue (page 32 from http://www.dmi.unict.it/diraimondo/uploads/classes/so/1213/SO-03-print.pdf)

The second line should read "pagine usate negli ultimi [DELTA] accessi alla memoria". Instead of DELTA, I get a EMPTYSET symbol. The same character occurs two other times in the page.
Similarly, in the middle it should read "D = [SUMMATION] WSSi" but, instead, I get a big black dot.

pdffonts -subst says
Symbol   433  0   Symbol   /usr/share/fonts/wine-symbol-fonts/symbol.ttf

If I uninstall wine, I can see the right characters, and pdffonts says:
Symbol   433  0   Standard Symbols L   /usr/share/fonts/default/Type1/s050000l.pfb
