/**
* \file
* \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 (http://icu-project.org/userguide/properties.html).
*
* 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 and ZWSP)
* - 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 - ZWSP
