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 + + See <A HREF="http://oss.software.ibm.com/icu/apiref/uchar_8h.html"> + this page</A> for full details. + +*******************************************************************************/ + +class UChar : ICU
