* 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. *
* Character information is based on the Unicode Standard, version 6.2.0. *
* The methods and data of class {@code Character} are defined by * the information in the UnicodeData 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. *
* The file and its description are available from the Unicode Consortium at: *
* *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 code points is now * U+0000 to U+10FFFF, known as Unicode scalar value. * (Refer to the * definition of the U+n notation in the Unicode * Standard.) * *
The set of characters from U+0000 to U+FFFF is * sometimes referred to as the Basic Multilingual Plane (BMP). * Characters whose code points are greater * than U+FFFF are called supplementary characters. 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 high-surrogates * range, (\uD800-\uDBFF), the second from the * low-surrogates range (\uDC00-\uDFFF). * *
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: * *
In the Java SE API documentation, Unicode code point is
* used for character values in the range between U+0000 and U+10FFFF,
* and Unicode code unit is used for 16-bit
* {@code char} values that are code units of the UTF-16
* encoding. For more information on Unicode terminology, refer to the
* Unicode Glossary.
