/**
* 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 5.1.0.
* <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:
* <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</code> data type (and therefore the value that a
* <code>Character</code> 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>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
* 2 platform uses the UTF-16 representation in <code>char</code>
* arrays and in the <code>String</code> and <code>StringBuffer</code>
* classes. In this representation, supplementary characters are
* represented as a pair of <code>char</code> 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</code> 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</code> value represents all Unicode code points,
* including supplementary code points. The lower (least significant)
* 21 bits of <code>int</code> 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</code> values is
* as follows:
*
* <ul>
* <li>The methods that only accept a <code>char</code> value cannot support
* supplementary characters. They treat <code>char</code> values from the
* surrogate ranges as undefined characters. For example,
* <code>Character.isLetter('&#92;uD840')</code> returns <code>false</code>, 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</code> value support all
* Unicode characters, including supplementary characters. For
* example, <code>Character.isLetter(0x2F81A)</code> returns
* <code>true</code> 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</code> 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>.

* <li> Canonical block names as defined by the Unicode Standard.
* For example, the standard defines a "Basic Latin" block. Therefore, this

* each UnicodeBlock provides the canonical name.
* <li>Canonical block names with all spaces removed. For example, "BasicLatin"
* is a valid block name for the "Basic Latin" block.
* <li>The text representation of each constant UnicodeBlock identifier.
* For example, this method will return the {@link #BASIC_LATIN} block if
* provided with the "BASIC_LATIN" name. This form replaces all spaces and
* hyphens in the canonical name with underscores.
* </ol>
* Finally, character case is ignored for all of the valid block name forms.
* For example, "BASIC_LATIN" and "basic_latin" are both valid block names.
* The en_US locale's case mapping rules are used to provide case-insensitive
