Myles has hinted that this might require implementing Font::applyTransforms for FreeType, though I'm not sure what all this entails. 1271093 1 mcatanzaro 2017-01-28 19:57:54 -0800 We should also investigate bug #102603, which I don't understand. 1283907 2 mcatanzaro 2017-03-06 13:23:38 -0800 *** Bug 149642 has been marked as a duplicate of this bug. *** 1419936 3 aperez 2018-05-02 17:20:43 -0700 As of r230559 (bug #183285) the GTK port is using always the complex text code path. Note that this is still relevant for other ports using FreeType (e.g. WPE). 1779684 4 mmaxfield 2021-07-26 22:21:29 -0700 I'm happy to work on this, as a part of https://bugs.webkit.org/show_bug.cgi?id=206208. I will need advice from someone who is more familiar with Harfbuzz, though. 1779727 5 mcatanzaro 2021-07-27 05:03:06 -0700 Hi, thanks for the offer to help. The simple text path does not use harfbuzz at all. harfbuzz is only used for the complex text path. (See bug #102603, which may or may not be obsolete, I'm not sure.) The simple text path uses FreeType directly. Well, at least I think so?

I don't know enough about FreeType to know whether this is actually possible. It's certainly a lot less important than it used to be since GTK no longer uses simple text at all, except when forced by environment variable, so nobody will ever see it. So this really only matters for WPE. I wonder if it's time for WPE to switch to the complex text path?
