/**
* 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, version 6.0.0.
* <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>
*
* <h4><a name="unicode">Unicode Character Representations</a></h4>
*
* <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 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>.
