I installed Inkscape, without any optional dependencies, using Pamac GUI on Plasma and noticed that all emojis in KDE applications (Konsole, Kate, Emoji picker) display as missing character rectangles. They work in Firefox just fine. Uninstalling Inkscape did not help, emojis remain broken.
Thankfully, I use timeshift, so I restored a snapshot I took an hour earlier and emojis work fine. Installed Inkscape again, emojis broken again. Restored the snapshot again, since I like having emojis in the terminal emulator.
How strange is that?
I have Inkscape on my laptop, which I installed a few months ago, and emojis there work fine.
These are the dependencies that get installed with Inkscape:
gsl-2.6-1 gtkmm-1:2.24.5-3 gtkspell-2.0.16-7 libcdr-0.1.6-1 libmagick6-184.108.40.206-1 librevenge-0.0.4-2 libwpd-0.10.3-1 poppler-glib-0.87.0-1 potrace-1.16-1 python2-2.7.17-2 ttf-dejavu-2.37-2
I'm suspecting the last one,
ttf-dejavu is the culprit. Maybe I should try installing only that, see if emojis are broken, and then restore the snapshot again, if so...
Yeah, that's the culprit: installing
ttf-dejavu breaks emojis in KDE applications. Removing it fixes emojis, no need to restore the snapshot.
