Exciting news for fans of typography!
"For decades, software like Adobe InDesign and LaTeX has evaluated multiple lines of text at a time as they decide where to end one line and begin the next. It’s just that the web didn’t use a multiline algorithm. Until now.
We are excited to bring this capability to the web for the first time, in Safari Technology Preview 216."
