[pdfcairo] which Symbol font?

Show all headers | View raw

using the pdfcairo terminal the Symbol font used is different from
what i'd expect

i agree that with pdfcairo's default font (sans-serif?) the greek symbols
from dejavusans are a better match than Adobe's symbol

what hurts is pdfcairo using the same the same dejavu font for greek
even if i change the main font to a serif font like, e.g., utopia,
producing a *significant visual impedance* (read buttugliness:-)

please see below for my test case, i'd like to know if it is a local
problem that i have to solve for myself or it is a standard behaviour

thank you in advance
