<bdo>
HTML <bdo> Tag
The HTML <bdo> tag (“bidirectional override”) sets the direction of a text output from right to left. It is used primarily with languages where reading occurs from right to left (e.g. Arabic).
The dir attribute is a required option for the <bdo> tag. It defines the direction within the <bdo> tag. It can have one of two values: ltr and rtl.
You should not use RTL words and phrases without markup. This can cause some problems. For isolating bidirectional text and avoiding display problems, you can use the <bdi> element.
HTML 4 did not specify events for the <bdo> element. They were added in XHTML.
