In attachments I enclose two files: texexec.pdf (created with pdflatex, and then pdf page selection is made by texexec) output.pdf (texexec.pdf printed by evince linked against cairo 1.12.12 into pdf file) You can see that the first symbol (mdash), which is presented in texexec.pdf is not present in output.pdf. The same procedure (printing into a pdf file) does work in a correct way if evince linked against cairo 1.12.2. So this is a regression.
Created attachment 74148 [details] original pdf file
Created attachment 74149 [details] the same pdf file printed by evince linked against cairo 1.12.12
Just for case, the version of the poppler in the system is 0.20.5
