  /**
   * The {@code Character} class wraps a value of the primitive
   * type {@code char} in an object. An object of type
   * {@code Character} contains a single field whose type is
   * {@code char}.
   * <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
   * <p>
   * The methods and data of class {@code Character} 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:
   * <ul>
   * <li><a href="http://www.unicode.org">http://www.unicode.org</a>
   * </ul>
   *
   * <h3><a name="unicode">Unicode Character Representations</a></h3>
   *
   * <p>The {@code char} data type (and therefore the value that a
   * {@code Character} object encapsulates) are based on the
   * original Unicode specification, which defined characters as
   * fixed-width 16-bit entities. The Unicode Standard has since been
   * changed to allow for characters whose representation requires more
   * than 16 bits.  The range of legal <em>code point</em>s is now
   * U+0000 to U+10FFFF, known as <em>Unicode scalar value</em>.
   * (Refer to the <a
   * href="http://www.unicode.org/reports/tr27/#notation"><i>
   * definition</i></a> of the U+<i>n</i> notation in the Unicode
   * Standard.)
   *
   * <p><a name="BMP">The set of characters from U+0000 to U+FFFF</a> is
   * sometimes referred to as the <em>Basic Multilingual Plane (BMP)</em>.
   * <a name="supplementary">Characters</a> whose code points are greater
   * than U+FFFF are called <em>supplementary character</em>s.  The Java
   * platform uses the UTF-16 representation in {@code char} arrays and
   * in the {@code String} and {@code StringBuffer} classes. In
   * this representation, supplementary characters are represented as a pair
   * of {@code char} values, the first from the <em>high-surrogates</em>
   * range, (&#92;uD800-&#92;uDBFF), the second from the
   * <em>low-surrogates</em> range (&#92;uDC00-&#92;uDFFF).
   *
   * <p>A {@code char} value, therefore, represents Basic
   * Multilingual Plane (BMP) code points, including the surrogate
   * code points, or code units of the UTF-16 encoding. An
   * {@code int} value represents all Unicode code points,
   * including supplementary code points. The lower (least significant)
   * 21 bits of {@code int} are used to represent Unicode code
   * points and the upper (most significant) 11 bits must be zero.
   * Unless otherwise specified, the behavior with respect to
   * supplementary characters and surrogate {@code char} values is
   * as follows:
   *
   * <ul>
   * <li>The methods that only accept a {@code char} value cannot support
   * supplementary characters. They treat {@code char} values from the
   * surrogate ranges as undefined characters. For example,
   * {@code Character.isLetter('\u005CuD840')} returns {@code false}, even though
   * this specific value if followed by any low-surrogate value in a string
   * would represent a letter.
   *
   * <li>The methods that accept an {@code int} value support all
   * Unicode characters, including supplementary characters. For
   * example, {@code Character.isLetter(0x2F81A)} returns
   * {@code true} because the code point value represents a letter
   * (a CJK ideograph).
   * </ul>
   *
   * <p>In the Java SE API documentation, <em>Unicode code point</em> is
   * used for character values in the range between U+0000 and U+10FFFF,
   * and <em>Unicode code unit</em> is used for 16-bit
   * {@code char} values that are code units of the <em>UTF-16</em>
   * encoding. For more information on Unicode terminology, refer to the
   * <a href="http://www.unicode.org/glossary/">Unicode Glossary</a>.
