unicodeBidi style property

Browser support:

Specifies or returns whether the text should be overridden to support multiple languages in the same document. Use with the direction property.

This property can override the Unicode standard algorithm of the browser that determines how text should appear when the page contains both RTL (right-to-left) and LTR (left-to-right) text.

Syntax:

object.unicodeBidi;
