Intended audience: users, HTML coders, script developers (PHP, JSP, etc.), CSS coders, Web project managers, and anyone who wants to know how language declarations work in current browsers.
These tests check whether user agents apply isolation around a sequence of plain text characters preceded by a Unicode directional control character that is one of RLI, LRI, or FSI, and followed by PDI. The browser should also treat the surrounded sequence of characters as a neutral character.
Note that the snapshot summaries of these test results are for released versions of the browsers tested. Versions that are still in development may provide better support for these features. The tests themselves do not test any vendor prefixes.
The tables show results for tests run on the date shown. Above the tables are summaries of the results at that date. The table data may be more up-to-date than the summary. If the tables contain some incorrectly scored tests, or tests that relate to non-released versions of browsers, these are not included in the summary.

No browser tested currently fully supports bidi isolation of elements with RLI/LRI/FSI...PDI. Chrome, Safari and Opera produce the expected ordering for only 6 of the 27 tests. Chrome and Opera have an additional problem in that they display the control characters as tofu. Links: Section 3.2.6 • Related tests
