Intended audience: users, XHTML/HTML coders (using editors or scripting), 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 internationalization aspects described in the HTML5 section about the
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.

bdo element with a
dir attribute works as expected on all browsers.
bdo element has no
dir attribute, although the spec says
Authors must specify the dir attribute on this element, with the value ltr to specify a left-to-right override and with the value rtl to specify a right-to-left override, only Safari followed the spec. All other browsers tested applied an override consistent with the direction of the parent element.
BR separates bidi paragraph
A br element should separate paragraphs for the purposes of the Unicode bidirectional algorithm.
BR in inline ancestors
A br element should separate paragraphs for the purposes of the Unicode bidirectional algorithm. If an inline element is broken around a bidi paragraph boundary (e.g. if split by a block or forced paragraph break), then the bidi control codes corresponding to the end of the element are added before the interruption and the codes corresponding to the start of the element are added after it. (In other words, any embedding levels or overrides started by the element are closed at the paragraph break and reopened on the other side of it.)
