But the render correctly with the “Noto Color Emoji” font. They are rendered correctly given the level of Unicode support, and what the font supports.

I'll let you file a separate bug about this problem. The Emoji One font is the default and recommended one because it's one for which the visual identity is not already used in another OS. The best way to get this problem fixed would be to work on a PNG-in-TTF build for the Emoji Two font. I currently don't have any time to work on this though. http://www.unicode.org/Public/emoji/4.0/emoji-zwj-sequences.txt already contained: 1F3CC 1F3FB 200D 2640 FE0F ; Emoji_ZWJ_Sequence ; woman golfing: light skin tone # 8.0 [1] (🏌🏻♀️) So this sequence was already there in Unicode 9.0.0.

This is how the broken sequences look like in "ibus emoji" when
using the "Emoji One" font.

But the render correctly with the “Noto Color Emoji” font. I am using Fedora-Workstation-netinst-x86_64-27-20170910.n.0.iso Installed in qemu using: nice -n 19 ionice -c 3 qemu-kvm -machine pc-i440fx-2.4 -enable-kvm -global qxl.ram_size=1x1024 -m 2048M -smp 2 -drive file=./Fedora-Workstation-netinst-x86_64-27-20170910.n.0.iso.qcow2,index=0,media=disk,cache=unsafe -localtime -serial file:/tmp/qemu-Fedora-Workstation-netinst-x86_64-27-20170910.n.0.iso.qcow2-output.log -name Fedora-Workstation-netinst-x86_64-27-20170910.n.0.iso.qcow2 -cdrom /local/mfabian/iso/Fedora-27/Fedora-Workstation-netinst-x86_64-27-20170910.n.0.iso -boot c -spice port=6002,disable-ticketing,streaming-video=off -vga qxl -display vnc=:6 -net nic -net user,hostname=Fedora-Workstation-netinst-x86_64-27-20170910.n.0.iso.qcow2,hostfwd=tcp::5558-:22 -monitor stdio -usb -usbdevice mouse -soundhw all [mfabian@Fedora-Workstation-netinst-x86_6 ~]$ rpm -q fontconfig pango cairo eosrei-emojione-fonts google-noto-emoji-fonts fontconfig-2.12.5-1.fc27.x86_64 pango-1.40.12-1.fc27.x86_64 cairo-1.15.8-1.fc27.x86_64 eosrei-emojione-fonts-1.0-5.fc27.noarch google-noto-emoji-fonts-20170827-1.fc27.noarch [mfabian@Fedora-Workstation-netinst-x86_6 ~]$ cat /etc/fedora-release Fedora release 27 (Twenty Seven) [mfabian@Fedora-Workstation-netinst-x86_6 ~]$ See attached screenshot. The left side of the screenshot shows font “Emoji One”. To make the right side of the screenshot, I removed the “Emoji One” font by doing sudo rpm -e --nodeps eosrei-emojione-fonts Then “Noto Color Emoji” will be used because it is the next available preferred emoji font in the fontconfig setup. With the “Noto Color Emoji” font, the rendering of all emoji sequences is perfect. On top of that, the “Noto Color Emoji” font has all the new emoji which have been added to Unicode 10.0.0 whereas “Emoji One” is only supporting the emoji which already were in Unicode 9.0.0. So maybe it would be a good idea to give “Noto Color Emoji” higher priority in the default fontconfig setup ...
