Apple's hyphenation API seems to behave odd, leading to suboptimal hyphenation in Safari and Chrome on Mac/iOS, see previous discussion at https://bugs.chromium.org/p/chromium/issues/detail?id=677263. Blink maintainer kojii states: OS X hyphenation API returns: "infrastructure" -> "in-frastructure" "frastructure" -> "fras-tructure" "tructure" -> "truc-ture" Attached a specific test case. Results: Safari on Mac: "in-frastructure" Firefox on Mac: "infrastruc-ture" (own dictionary) Safari on Windows: "infrastruc-ture"
Created attachment 298181 [details] Test Case
Could you please file the bug via <https://bugreport.apple.com>? WebKit bugzilla is for WebKit bugs only, and while I can copy the bug for Apple, that would break the link to you as the reporter.
Ok, reported it over at bugreport.apple.com, ID 29944454.
