BidiType represents the bidirectional character type of a Unicode character.

The values in this enumeration are specified by the Unicode bidirectional algorithm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
