arrow-style data type
The arrow-style type represents the style of an arrow, using Unicode arrow terminology. Filled and hollow arrows indicate polygonal single arrows. Paired arrows are duplicate single arrows in the same direction. Combined arrows apply to double direction arrows like left right, indicating that an arrow in one direction should be combined with an arrow in the other direction.
