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
