I recently updated to 20.04 and I love the new full range of full color emoji but they disappear when I print, export to PDF or even if I download a pdf from email.
I thought it was a libre office issue at first until I noticed them disappear from the downloaded PDF. In the screencapture is a Libre office spreadsheet print preview screen full of emoji, and on the right is what I get if I export to PDF or print.
I have verified that "objects/images" is checked in LibreOffice, tried from a fresh file, and tried it in LibreOffice's safe mode. Please help.
