Detailed Description

Represents a Unicode character (as a UTF-32 char32_t code point).

Provides static methods for classifying Unicode characters, converting between upper/lower cases, validating ASCII and Latin-1 ranges, and querying numeric values. Immutable value type; thread-safe for all operations.

Note: Conforms to ECMA-335 Partition IV Section 5.13 (System.Char) and Unicode 15.0.
