/**
* \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://oss.software.ibm.com/icu/userguide/properties.html).
*
* Many functions are designed to match java.lang.Character functions.
* See the individual function documentation,
* and see the JDK 1.4.1 java.lang.Character documentation
* at http://java.sun.com/j2se/1.4.1/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.
*
* A summary of the behavior of some C/POSIX character classification implementations
* for Unicode is available at http://oss.software.ibm.com/cvs/icu/~checkout~/icuhtml/design/posix_classes.html
*
* <strong>Important</strong>:
* The behavior of the ICU C/POSIX-style character classification
* functions is subject to change according to discussion of the above summary.
*
* 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
