On Mac there are a bunch of emoji there, but on GTK there are only placeholder characters shown. Something in the GTK stack doesn't support these new emoji properly. 1239163 1 bugzilla 2016-10-11 21:11:13 -0700 Duplicate of 156579? 1239321 2 mcatanzaro 2016-10-12 09:33:08 -0700 I'm not sure. I would assume bug #156579 would be just about adding color to the emoji. The emoji in this test are not drawn properly at all. 1363804 3 aperez 2017-10-24 12:09:33 -0700 (In reply to Michael Catanzaro from comment #0) > I'm skipping the layout test editing/deleting/delete-emoji.html because it > doesn't have expected results yet, and the actual results I see do not look > reasonable.

Today I have been able to verify that the output for the GTK+ port matches that of the Mac port for the following tests: * editing/deleting/delete-emoji.html * editing/deleting/delete-emoji-1.html I'll add the expectations and unskip these two only, and check the rest of the emoji deletion tests later on. 1364143 4 aperez 2017-10-25 01:05:50 -0700 (In reply to Adrian Perez from comment #3) > [...] > * editing/deleting/delete-emoji.html > * editing/deleting/delete-emoji-1.html > > I'll add the expectations and unskip these two only, and check the rest of > the emoji deletion tests later on. Done in bug #178742 1364944 5 mmaxfield 2017-10-26 11:43:09 -0700 https://trac.webkit.org/changeset/223578/webkit This is the patch which caused this. This patch removes custom character-iteration code inside RenderText in favor of platform-supplied character iterators. On GTK, this would take the form of ubrk_ ICU functions using the CHARACTER enum. The best thing to do would be to verify that the deletion behavior matches some other native app on GTK, and if so, generate expected results. 2168146 6 csaavedra 2025-12-25 04:27:04 -0800 All tests referencing this bug now pass, I am unskipping them and closing this one soon. 2168147 7 csaavedra 2025-12-25 04:33:40 -0800 Pull request: https://github.com/WebKit/WebKit/pull/55863 2168165 8 ews-feeder 2025-12-25 08:15:14 -0800 Test gardening commit 304935@main (89935439d6da): <https://commits.webkit.org/304935@main> Reviewed commits have been landed.
