67 * \brief C API: Unicode Properties
68 *
69 * This C API provides low-level access to the Unicode Character Database.
70 * In addition to raw property values, some convenience functions calculate
71 * derived properties, for example for Java-style programming.
72 *
73 * Unicode assigns each code point (not just assigned character) values for
74 * many properties.
75 * Most of them are simple boolean flags, or constants from a small enumerated list.
76 * For some properties, values are strings or other relatively more complex types.
77 *
78 * For more information see
79 * "About the Unicode Character Database" (http://www.unicode.org/ucd/)
80 * and the ICU User Guide chapter on Properties (http://icu-project.org/userguide/properties.html).
81 *
82 * Many properties are accessible via generic functions that take a UProperty selector.
83 * - u_hasBinaryProperty() returns a binary value (TRUE/FALSE) per property and code point.
84 * - u_getIntPropertyValue() returns an integer value per property and code point.
85 * For each supported enumerated or catalog property, there is
86 * an enum type for all of the property's values, and
87 * u_getIntPropertyValue() returns the numeric values of those constants.
88 * - u_getBinaryPropertySet() returns a set for each ICU-supported binary property with
89 * all code points for which the property is true.
90 * - u_getIntPropertyMap() returns a map for each
91 * ICU-supported enumerated/catalog/int-valued property which
92 * maps all Unicode code points to their values for that property.
93 *
94 * Many functions are designed to match java.lang.Character functions.
95 * See the individual function documentation,
96 * and see the JDK 1.4 java.lang.Character documentation
97 * at http://java.sun.com/j2se/1.4/docs/api/java/lang/Character.html
98 *
99 * There are also functions that provide easy migration from C/POSIX functions
100 * like isblank(). Their use is generally discouraged because the C/POSIX
101 * standards do not define their semantics beyond the ASCII range, which means
102 * that different implementations exhibit very different behavior.
103 * Instead, Unicode properties should be used directly.
104 *
105 * There are also only a few, broad C/POSIX character classes, and they tend
106 * to be used for conflicting purposes. For example, the "isalpha()" class
107 * is sometimes used to determine word boundaries, while a more sophisticated
108 * approach would at least distinguish initial letters from continuation
109 * characters (the latter including combining marks).
110 * (In ICU, BreakIterator is the most sophisticated API for word boundaries.)
111 * Another example: There is no "istitle()" class for titlecase characters.
112 *
113 * ICU 3.4 and later provides API access for all twelve C/POSIX character classes.
114 * ICU implements them according to the Standard Recommendations in
115 * Annex C: Compatibility Properties of UTS #18 Unicode Regular Expressions
116 * (http://www.unicode.org/reports/tr18/#Compatibility_Properties).
117 *
118 * API access for C/POSIX character classes is as follows:
119 * - alpha: u_isUAlphabetic(c) or u_hasBinaryProperty(c, UCHAR_ALPHABETIC)
120 * - lower: u_isULowercase(c) or u_hasBinaryProperty(c, UCHAR_LOWERCASE)
121 * - upper: u_isUUppercase(c) or u_hasBinaryProperty(c, UCHAR_UPPERCASE)
122 * - punct: u_ispunct(c)
123 * - digit: u_isdigit(c) or u_charType(c)==U_DECIMAL_DIGIT_NUMBER
124 * - xdigit: u_isxdigit(c) or u_hasBinaryProperty(c, UCHAR_POSIX_XDIGIT)
125 * - alnum: u_hasBinaryProperty(c, UCHAR_POSIX_ALNUM)
126 * - space: u_isUWhiteSpace(c) or u_hasBinaryProperty(c, UCHAR_WHITE_SPACE)
127 * - blank: u_isblank(c) or u_hasBinaryProperty(c, UCHAR_POSIX_BLANK)
128 * - cntrl: u_charType(c)==U_CONTROL_CHAR
129 * - graph: u_hasBinaryProperty(c, UCHAR_POSIX_GRAPH)
130 * - print: u_hasBinaryProperty(c, UCHAR_POSIX_PRINT)
131 *
132 * Note: Some of the u_isxyz() functions in uchar.h predate, and do not match,
133 * the Standard Recommendations in UTS #18. Instead, they match Java
134 * functions according to their API documentation.
135 *
136 * \htmlonly
137 * The C/POSIX character classes are also available in UnicodeSet patterns,
138 * using patterns like [:graph:] or \p{graph}.
139 * \endhtmlonly
140 *
141 * Note: There are several ICU whitespace functions.
142 * Comparison:
143 * - u_isUWhiteSpace=UCHAR_WHITE_SPACE: Unicode White_Space property;
144 * most of general categories "Z" (separators) + most whitespace ISO controls
145 * (including no-break spaces, but excluding IS1..IS4)
146 * - u_isWhitespace: Java isWhitespace; Z + whitespace ISO controls but excluding no-break spaces
147 * - u_isJavaSpaceChar: Java isSpaceChar; just Z (including no-break spaces)
148 * - u_isspace: Z + whitespace ISO controls (including no-break spaces)
149 * - u_isblank: "horizontal spaces" = TAB + Zs

2690 * Unicode, especially in version 3.2, defines many more properties than the

2695 * For details about the properties see http://www.unicode.org/ .
2696 * For names of Unicode properties see the UCD file PropertyAliases.txt.

2699 * UEastAsianWidth ea=(UEastAsianWidth)u_getIntPropertyValue(c, UCHAR_EAST_ASIAN_WIDTH);
2700 * UBool b=(UBool)u_getIntPropertyValue(c, UCHAR_IDEOGRAPHIC);
2701 *
2702 * @param c Code point to test.
2703 * @param which UProperty selector constant, identifies which property to check.
2704 * Must be UCHAR_BINARY_START<=which<UCHAR_BINARY_LIMIT
2705 * or UCHAR_INT_START<=which<UCHAR_INT_LIMIT
2706 * or UCHAR_MASK_START<=which<UCHAR_MASK_LIMIT.
2707 * @return Numeric value that is directly the property value or,
2708 * for enumerated properties, corresponds to the numeric value of the enumerated
2709 * constant of the respective property value enumeration type
2710 * (cast to enum type if necessary).
2711 * Returns 0 or 1 (for FALSE/TRUE) for binary Unicode properties.
2712 * Returns a bit-mask for mask properties.
2713 * Returns 0 if 'which' is out of bounds or if the Unicode version
2714 * does not have data for the property at all, or not for this code point.
