An object of type + * {@code Character} contains a single field whose type is + * {@code char}. + *
+ * 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 6.0.0. + *
+ * 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.
