I have now tested with current git master
(last commit 35d0675467e61aff30c21544f87f55b1b1a2cfd3) and it is much
better!

Thank you very much!

I could still find one sequence which doesn‘t work though:

🏴‍☠ U+1F3F4 U+200D U+2620 pirate flag

Works in gedit (i.e. it works in pango/cairo/harfbuzz), see screenshot.
