public int MaximumBidiReorderingDepth { get; }

Property Value

Every time there's left-to-right script embedded within right-to-left script, or vice-versa, that represents one 'bidi' (bi-directional text) re-ordering level. Changes of script direction can be nested within one another. This property gets the maximum level of such nesting which exists anywhere in the text layout.

As a convention, if there is no text or if the script doesn't change directions, this property is 1.
