Cyrillic letters display as rectangles
I have two pretty similar files which use the same base font: Chertezh_v15.pdf displays well, while Chertezh_V16.pdf renders Cyrillic characters as rectangle placeholders (tofu) in poppler 2021.3 (tried SVG and PNG output). Both files display well in Adobe Reader and Chrome.
Screenshot: poppler-png-results
Both files were created by "Compass 3D" software, v15 and v16 correspondingly.
Any idea on what is wrong or unsupported by poppler in the v16 file?
Steps to reproduce:
- Pull archlinux docker image
- Install poppler using
pacman -Sy poppler
command. Pdftocairo reports its version as21.03.0
. - run
pdftocairo -png -l 1 -f 1 Chertezh_v15.pdf Chertezh_V15.pdf.p2103.png
- result is OK, Cyrillic characters are displayed correctly - run
pdftocairo -png -l 1 -f 1 Chertezh_V16.pdf Chertezh_V16.pdf.p2103.png
- result is NOT OK, Cyrillic characters are displayed as tofu
Result PNGs are attached: Chertezh_V15.pdf.p2103.png-1, Chertezh_V16.pdf.p2103.png-1
Upd: In my initial message I listed the files in wrong order, maybe that's why I've got "can't reproduce" replies.
