Etymology
z (axis) + variant; from the three dimensions visualized for the character space. The x-axis separates characters by semantics (function and meaning, e.g. A from B), the y-axis separates them by their general form (abstract shape, e.g. A from a), and the z-axis by their actual shape (minor details such as typeface, e.g. a from a).
Noun
z-variant (plural: z-variants )
- (Unicode) a shape variant of a Han character, encoded for historical reasons.
