An object of type 37 * {@code Character} contains a single field whose type is 38 * {@code char}. 39 * <p> 40 * In addition, this class provides several methods for determining 41 * a character's category (lowercase letter, digit, etc.) and for converting 42 * characters from uppercase to lowercase and vice versa. 43 * <p> 44 * Character information is based on the Unicode Standard, version 6.2.0. 45 * <p> 46 * The methods and data of class {@code Character} are defined by 47 * the information in the <i>UnicodeData</i> file that is part of the 48 * Unicode Character Database maintained by the Unicode 49 * Consortium. This file specifies various properties including name 50 * and general category for every defined Unicode code point or 51 * character range. 52 * <p> 53 * The file and its description are available from the Unicode Consortium at: 54 * <ul> 55 * <li><a href="http://www.unicode.org">http://www.unicode.org</a> 56 * </ul> 57 * 58 * <h3><a name="unicode">Unicode Character Representations</a></h3> 59 * 60 * <p>The {@code char} data type (and therefore the value that a 61 * {@code Character} object encapsulates) are based on the 62 * original Unicode specification, which defined characters as 63 * fixed-width 16-bit entities. The Unicode Standard has since been 64 * changed to allow for characters whose representation requires more 65 * than 16 bits. The range of legal <em>code point</em>s is now 66 * U+0000 to U+10FFFF, known as <em>Unicode scalar value</em>. 67 * (Refer to the <a 68 * href="http://www.unicode.org/reports/tr27/#notation"><i> 69 * definition</i></a> of the U+<i>n</i> notation in the Unicode 70 * Standard.) 71 * 72 * <p><a name="BMP">The set of characters from U+0000 to U+FFFF</a> is 73 * sometimes referred to as the <em>Basic Multilingual Plane (BMP)</em>. 74 * <a name="supplementary">Characters</a> whose code points are greater 75 * than U+FFFF are called <em>supplementary character</em>s. The Java 76 * platform uses the UTF-16 representation in {@code char} arrays and 77 * in the {@code String} and {@code StringBuffer} classes. In 78 * this representation, supplementary characters are represented as a pair 79 * of {@code char} values, the first from the <em>high-surrogates</em> 80 * range, (\uD800-\uDBFF), the second from the 81 * <em>low-surrogates</em> range (\uDC00-\uDFFF). 82 * 83 * <p>A {@code char} value, therefore, represents Basic 84 * Multilingual Plane (BMP) code points, including the surrogate 85 * code points, or code units of the UTF-16 encoding. An 86 * {@code int} value represents all Unicode code points, 87 * including supplementary code points. The lower (least significant) 88 * 21 bits of {@code int} are used to represent Unicode code 89 * points and the upper (most significant) 11 bits must be zero. 90 * Unless otherwise specified, the behavior with respect to 91 * supplementary characters and surrogate {@code char} values is 92 * as follows: 93 * 94 * <ul> 95 * <li>The methods that only accept a {@code char} value cannot support 96 * supplementary characters. They treat {@code char} values from the 97 * surrogate ranges as undefined characters. For example, 98 * {@code Character.isLetter('\u005CuD840')} returns {@code false}, even though 99 * this specific value if followed by any low-surrogate value in a string 100 * would represent a letter. 101 * 102 * <li>The methods that accept an {@code int} value support all 103 * Unicode characters, including supplementary characters. For 104 * example, {@code Character.isLetter(0x2F81A)} returns 105 * {@code true} because the code point value represents a letter 106 * (a CJK ideograph). 107 * </ul> 108 * 109 * <p>In the Java SE API documentation, <em>Unicode code point</em> is 110 * used for character values in the range between U+0000 and U+10FFFF, 111 * and <em>Unicode code unit</em> is used for 16-bit 112 * {@code char} values that are code units of the <em>UTF-16</em> 113 * encoding.
