There's no guarantee for it.
The kTraditionalVariant and kSimplifiedVariant should be symmetrical with
respect to each other (if U+XXXX is a kTraditionalVariant for U+YYYY, then
U+YYYY should be a kSimplifiedVariant for U+XXXX).
kCompatibilityVariant is expressly *not* symmetrical.
kSemanticVariant should reasonably be symmetrical, but there is no
guarantee. The same is true for kZVariant.

X-variants are two characters with different abstract shapes and different
meanings. Y-variants are characters with the same meaning but different
abstract shapes.

The Unicode Standard, version 3.0, pp. 262-263.
