This seemingly valid PDF gets curiously broken, when converted by pdftocairo into level 3 PS or PDF, letters i and l are missing from the result. Cairo 1.14.12, poppler-utils 0.53.0, both commands produce a resulting PDF or PS where letters i and l are missing: pdftocairo -ps -level3 isandlsmissing.pdf is-cairo53.ps pdftocairo -pdf isandlsmissing.pdf is-cairo53.pdf Same commands produce correct files on Ubuntu 14.04, cairo 1.13.1, poppler-utils 0.24.5. pdftocairo -ps -level3 isandlsmissing.pdf is-cairo24.ps pdftocairo -pdf isandlsmissing.pdf is-cairo24.pdf Original PDF was validated with Adobe Pro DC, no syntax errors found.

Perhaps someone could have a quick look at this weird bug?

Thanks so much, Jason! That was it. I backported a patch for my 1.14.12 from https://bugs.launchpad.net/ubuntu/+source/cairo/+bug/1734092 and it fixed the issue. *** This bug has been marked as a duplicate of bug 94615 ***
