Description Thomas Bachem 2017-01-06 00:46:16 PST 
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"

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.
