kCTTypesetterOptionDisableBidiProcessing

Declaration

let kCTTypesetterOptionDisableBidiProcessing: CFString

Discussion

Disables bidirectional processing. Value must be a CFBoolean object. Default value is false. Normally, typesetting applies the Unicode Bidirectional Algorithm as described in Unicode Standard Annex #9. If a typesetter is created with this option set to true, no directional reordering is performed, and any directional control characters are ignored.
