Completed a fresh install and update of 18.04.2 64-bit last week.
It's perfectly fine. Except many emojis are gone from whatever Noto pack Librewriter uses. I'd like them back. Included below is a picture of the issue.
As you can see, it calls the location of the emoji just fine, but there doesn't seem to be any data in that part of the font pack that Librewriter would care to display. Not a � but a tall empty rectangle replaces most my emojis.
This is also the case in all my
.odt docs. They have an empty rectangle where the emojis used to be before this fresh install, update, and restart.
gedit displays emojis from
Right Click > Insert Emoji just fine.
I have no idea what information you need, but i hope this is a good start.
