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
