* The Character class wraps a value of the primitive
* type char in an object. An object of type
* Character contains a single field whose type is
* char.
*
* In addition, this class provides several methods for determining
* a character's category (lowercase letter, digit, etc.) and for converting
* characters from uppercase to lowercase and vice versa.
*
* Character information is based on the Unicode Standard, version 3.0.
*
* The methods and data of class Character are defined by
* the information in the UnicodeData file that is part of the
* Unicode Character Database maintained by the Unicode
* Consortium. This file specifies various properties including name
* and general category for every defined Unicode code point or
* character range.
