 * \brief C API: Unicode Properties
 *
 * This C API provides low-level access to the Unicode Character Database.
 * In addition to raw property values, some convenience functions calculate
 * derived properties, for example for Java-style programming.
 *
 * Unicode assigns each code point (not just assigned character) values for
 * many properties.
 * Most of them are simple boolean flags, or constants from a small enumerated list.
 * For some properties, values are strings or other relatively more complex types.
 *
 * For more information see
 * "About the Unicode Character Database" (http://www.unicode.org/ucd/)
 * and the ICU User Guide chapter on Properties (https://unicode-org.github.io/icu/userguide/strings/properties).
 *
 * Many properties are accessible via generic functions that take a UProperty selector.
 * - u_hasBinaryProperty() returns a binary value (true/false) per property and code point.
 * - u_getIntPropertyValue() returns an integer value per property and code point.
 *   For each supported enumerated or catalog property, there is
 *   an enum type for all of the property's values, and
 *   u_getIntPropertyValue() returns the numeric values of those constants.
 * - u_getBinaryPropertySet() returns a set for each ICU-supported binary property with
 *   all code points for which the property is true.
 * - u_getIntPropertyMap() returns a map for each
 *   ICU-supported enumerated/catalog/int-valued property which
 *   maps all Unicode code points to their values for that property.
 *
 * Many functions are designed to match java.lang.Character functions.
 * See the individual function documentation,
 * and see the JDK 1.4 java.lang.Character documentation
 * at http://java.sun.com/j2se/1.4/docs/api/java/lang/Character.html
 *
 * There are also functions that provide easy migration from C/POSIX functions
 * like isblank(). Their use is generally discouraged because the C/POSIX
 * standards do not define their semantics beyond the ASCII range, which means
 * that different implementations exhibit very different behavior.
 * Instead, Unicode properties should be used directly.
 *
 * There are also only a few, broad C/POSIX character classes, and they tend
 * to be used for conflicting purposes. For example, the "isalpha()" class
 * is sometimes used to determine word boundaries, while a more sophisticated
 * approach would at least distinguish initial letters from continuation
 * characters (the latter including combining marks).
 * (In ICU, BreakIterator is the most sophisticated API for word boundaries.)
 * Another example: There is no "istitle()" class for titlecase characters.
 *
 * ICU 3.4 and later provides API access for all twelve C/POSIX character classes.
 * ICU implements them according to the Standard Recommendations in
 * Annex C: Compatibility Properties of UTS #18 Unicode Regular Expressions
 * (http://www.unicode.org/reports/tr18/#Compatibility_Properties).
 *
 * API access for C/POSIX character classes is as follows:
 * - alpha:     u_isUAlphabetic(c) or u_hasBinaryProperty(c, UCHAR_ALPHABETIC)
 * - lower:     u_isULowercase(c) or u_hasBinaryProperty(c, UCHAR_LOWERCASE)
 * - upper:     u_isUUppercase(c) or u_hasBinaryProperty(c, UCHAR_UPPERCASE)
 * - punct:     u_ispunct(c)
 * - digit:     u_isdigit(c) or u_charType(c)==U_DECIMAL_DIGIT_NUMBER
 * - xdigit:    u_isxdigit(c) or u_hasBinaryProperty(c, UCHAR_POSIX_XDIGIT)
 * - alnum:     u_hasBinaryProperty(c, UCHAR_POSIX_ALNUM)
 * - space:     u_isUWhiteSpace(c) or u_hasBinaryProperty(c, UCHAR_WHITE_SPACE)
 * - blank:     u_isblank(c) or u_hasBinaryProperty(c, UCHAR_POSIX_BLANK)
 * - cntrl:     u_charType(c)==U_CONTROL_CHAR
 * - graph:     u_hasBinaryProperty(c, UCHAR_POSIX_GRAPH)
 * - print:     u_hasBinaryProperty(c, UCHAR_POSIX_PRINT)
 *
 * Note: Some of the u_isxyz() functions in uchar.h predate, and do not match,
 * the Standard Recommendations in UTS #18. Instead, they match Java
 * functions according to their API documentation.
 *
 * \htmlonly
 * The C/POSIX character classes are also available in UnicodeSet patterns,
 * using patterns like [:graph:] or \p{graph}.
 * \endhtmlonly
 *
 * Note: There are several ICU whitespace functions.
 * Comparison:
 * - u_isUWhiteSpace=UCHAR_WHITE_SPACE: Unicode White_Space property;
 *       most of general categories "Z" (separators) + most whitespace ISO controls
 *       (including no-break spaces, but excluding IS1..IS4)
 * - u_isWhitespace: Java isWhitespace; Z + whitespace ISO controls but excluding no-break spaces
 * - u_isJavaSpaceChar: Java isSpaceChar; just Z (including no-break spaces)
 * - u_isspace: Z + whitespace ISO controls (including no-break spaces)
 * - u_isblank: "horizontal spaces" = TAB + Zs
