Summarized test results:
CSS Text, Line-breaking

Intended audience: users, HTML coders, script developers, CSS coders, Web project managers, and anyone who wants to know how well browsers support the line breaking properties of Unicode characters.

These tests check the default line-breaking behavior of characters against the expectations in the Unicode Standard, version 10. With a very few exceptions, the CSS3 Text specification leaves it up to the browser to decide how these characters should behave. In many cases, the behaviour may depend on context. These tests explore how the browsers handle the various line break related characters by default.
