46 * \brief C API: Unicode Properties
47 *
48 * This C API provides low-level access to the Unicode Character Database.
49 * In addition to raw property values, some convenience functions calculate
50 * derived properties, for example for Java-style programming.
51 *
52 * Unicode assigns each code point (not just assigned character) values for
53 * many properties.
54 * Most of them are simple boolean flags, or constants from a small enumerated list.
55 * For some properties, values are strings or other relatively more complex types.
56 *
57 * For more information see
58 * "About the Unicode Character Database" (http://www.unicode.org/ucd/)
59 * and the ICU User Guide chapter on Properties (http://icu-project.org/userguide/properties.html).
60 *
61 * Many functions are designed to match java.lang.Character functions.
62 * See the individual function documentation,
63 * and see the JDK 1.4 java.lang.Character documentation
64 * at http://java.sun.com/j2se/1.4/docs/api/java/lang/Character.html
65 *
66 * There are also functions that provide easy migration from C/POSIX functions
67 * like isblank(). Their use is generally discouraged because the C/POSIX
68 * standards do not define their semantics beyond the ASCII range, which means
69 * that different implementations exhibit very different behavior.
70 * Instead, Unicode properties should be used directly.
71 *
72 * There are also only a few, broad C/POSIX character classes, and they tend
73 * to be used for conflicting purposes. For example, the "isalpha()" class
74 * is sometimes used to determine word boundaries, while a more sophisticated
75 * approach would at least distinguish initial letters from continuation
76 * characters (the latter including combining marks).
77 * (In ICU, BreakIterator is the most sophisticated API for word boundaries.)
78 * Another example: There is no "istitle()" class for titlecase characters.
79 *
80 * ICU 3.4 and later provides API access for all twelve C/POSIX character classes.
81 * ICU implements them according to the Standard Recommendations in
82 * Annex C: Compatibility Properties of UTS #18 Unicode Regular Expressions
83 * (http://www.unicode.org/reports/tr18/#Compatibility_Properties).
84 *
85 * API access for C/POSIX character classes is as follows:
86 * - alpha: u_isUAlphabetic(c) or u_hasBinaryProperty(c, UCHAR_ALPHABETIC)
87 * - lower: u_isULowercase(c) or u_hasBinaryProperty(c, UCHAR_LOWERCASE)
88 * - upper: u_isUUppercase(c) or u_hasBinaryProperty(c, UCHAR_UPPERCASE)
89 * - punct: u_ispunct(c)
90 * - digit: u_isdigit(c) or u_charType(c)==U_DECIMAL_DIGIT_NUMBER
91 * - xdigit: u_isxdigit(c) or u_hasBinaryProperty(c, UCHAR_POSIX_XDIGIT)
92 * - alnum: u_hasBinaryProperty(c, UCHAR_POSIX_ALNUM)
93 * - space: u_isUWhiteSpace(c) or u_hasBinaryProperty(c, UCHAR_WHITE_SPACE)
94 * - blank: u_isblank(c) or u_hasBinaryProperty(c, UCHAR_POSIX_BLANK)
95 * - cntrl: u_charType(c)==U_CONTROL_CHAR
96 * - graph: u_hasBinaryProperty(c, UCHAR_POSIX_GRAPH)
97 * - print: u_hasBinaryProperty(c, UCHAR_POSIX_PRINT)
98 *
99 * Note: Some of the u_isxyz() functions in uchar.h predate, and do not match,
100 * the Standard Recommendations in UTS #18. Instead, they match Java
101 * functions according to their API documentation.
102 *
103 * \htmlonly
104 * The C/POSIX character classes are also available in UnicodeSet patterns,
105 * using patterns like [:graph:] or \p{graph}.
106 * \endhtmlonly
107 *
108 * Note: There are several ICU whitespace functions.
109 * Comparison:
110 * - u_isUWhiteSpace=UCHAR_WHITE_SPACE: Unicode White_Space property;
111 * most of general categories "Z" (separators) + most whitespace ISO controls
112 * (including no-break spaces, but excluding IS1..IS4 and ZWSP)
113 * - u_isWhitespace: Java isWhitespace; Z + whitespace ISO controls but excluding no-break spaces
114 * - u_isJavaSpaceChar: Java isSpaceChar; just Z (including no-break spaces)
115 * - u_isspace: Z + whitespace ISO controls (including no-break spaces)
116 * - u_isblank: "horizontal spaces" = TAB + Zs - ZWSP
