/**
 * The <code>Character</code> class wraps a value of the primitive
 * type <code>char</code> in an object. An object of type
 * <code>Character</code> contains a single field whose type is
 * <code>char</code>.
 * <p>
 * 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.
 * <p>
 * Character information is based on the Unicode Standard, version 3.0.
 * <p>
 * The methods and data of class <code>Character</code> are defined by
 * the information in the <i>UnicodeData</i> 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.
 * <p>
 * The file and its description are available from the Unicode Consortium at:
