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.
To see details about which characters are tested and which fail, click on the link in the left column to view the test.
The two-letter abbreviations are conventions for property names in the Unicode Standard. For more information about expected line break behavior and line break classes, see Unicode Standard Annex #14 Line Breaking Properties.
To see the test, click on the link in the left-most column. To see detailed results for a single test, click on a row and look just above the table. The detailed results show the date(s) the test result was recorded, and the version of the browser tested.
In all these tests, one would expect a line to break after the character being tested.
These tests look at what should or shouldn't appear at the start or end of a line.
