/**
 * <strong>[icu enhancement]</strong> ICU's replacement for {@link java.lang.Character}.&nbsp;Methods, fields, and other functionality specific to ICU are labeled '<strong>[icu]</strong>'.
 *
 * <p>The UCharacter class provides extensions to the {@link java.lang.Character} class.
 * These extensions provide support for more Unicode properties.
 * Each ICU release supports the latest version of Unicode available at that time.
 *
 * <p>For some time before Java 5 added support for supplementary Unicode code points,
 * The ICU UCharacter class and many other ICU classes already supported them.
 * Some UCharacter methods and constants were widened slightly differently than
 * how the Character class methods and constants were widened later.
 * In particular, {@link Character#MAX_VALUE} is still a char with the value U+FFFF,
 * while the {@link UCharacter#MAX_VALUE} is an int with the value U+10FFFF.
 *
 * <p>Code points are represented in these API using ints. While it would be
 * more convenient in Java to have a separate primitive datatype for them,
 * ints suffice in the meantime.
 *
 * <p>Aside from the additions for UTF-16 support, and the updated Unicode
 * properties, the main differences between UCharacter and Character are:
 * <ul>
 * <li> UCharacter is not designed to be a char wrapper and does not have
 *      APIs to which involves management of that single char.<br>
 *      These include:
 *      <ul>
 *        <li> char charValue(),
 *        <li> int compareTo(java.lang.Character, java.lang.Character), etc.
 *      </ul>
 * <li> UCharacter does not include Character APIs that are deprecated, nor
 *      does it include the Java-specific character information, such as
 *      boolean isJavaIdentifierPart(char ch).
 * <li> Character maps characters 'A' - 'Z' and 'a' - 'z' to the numeric
 *      values '10' - '35'. UCharacter also does this in digit and
 *      getNumericValue, to adhere to the java semantics of these
 *      methods.  New methods unicodeDigit, and
 *      getUnicodeNumericValue do not treat the above code points
 *      as having numeric values.  This is a semantic change from ICU4J 1.3.1.
 * </ul>
 * <p>
 * In addition to Java compatibility functions, which calculate derived properties,
 * this API provides low-level access to the Unicode Character Database.
 * <p>
 * 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.
 * <p>
 * For more information see
 * <a href="http://www.unicode/org/ucd/">"About the Unicode Character Database"</a>
 * (http://www.unicode.org/ucd/)
 * and the <a href="http://www.icu-project.org/userguide/properties.html">ICU
 * User Guide chapter on Properties</a>
 * (http://www.icu-project.org/userguide/properties.html).
 * <p>
 * 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.
 * <p>
 * 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.
 * <p>
 * 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).
 * <p>
 * API access for C/POSIX character classes is as follows:
 * <pre>{@code
 * - alpha:     isUAlphabetic(c) or hasBinaryProperty(c, UProperty.ALPHABETIC)
 * - lower:     isULowercase(c) or hasBinaryProperty(c, UProperty.LOWERCASE)
 * - upper:     isUUppercase(c) or hasBinaryProperty(c, UProperty.UPPERCASE)
 * - punct:     ((1<<getType(c)) & ((1<<DASH_PUNCTUATION)|(1<<START_PUNCTUATION)|
 *               (1<<END_PUNCTUATION)|(1<<CONNECTOR_PUNCTUATION)|(1<<OTHER_PUNCTUATION)|
 *               (1<<INITIAL_PUNCTUATION)|(1<<FINAL_PUNCTUATION)))!=0
 * - digit:     isDigit(c) or getType(c)==DECIMAL_DIGIT_NUMBER
 * - xdigit:    hasBinaryProperty(c, UProperty.POSIX_XDIGIT)
 * - alnum:     hasBinaryProperty(c, UProperty.POSIX_ALNUM)
 * - space:     isUWhiteSpace(c) or hasBinaryProperty(c, UProperty.WHITE_SPACE)
 * - blank:     hasBinaryProperty(c, UProperty.POSIX_BLANK)
 * - cntrl:     getType(c)==CONTROL
 * - graph:     hasBinaryProperty(c, UProperty.POSIX_GRAPH)
 * - print:     hasBinaryProperty(c, UProperty.POSIX_PRINT)}</pre>
 * <p>
 * The C/POSIX character classes are also available in UnicodeSet patterns,
 * using patterns like [:graph:] or \p{graph}.
 *
 * <p><strong>[icu] Note:</strong> There are several ICU (and Java) whitespace functions.
 * Comparison:<ul>
 * <li> 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)
 * <li> isWhitespace: Java isWhitespace; Z + whitespace ISO controls but excluding no-break spaces
 * <li> isSpaceChar: just Z (including no-break spaces)</ul>
 *
 * <p>
 * This class is not subclassable.
