[icu enhancement] ICU's replacement for java.lang.Character. Methods, fields, and other functionality specific to ICU are labeled '[icu]'.

The UCharacter class provides extensions to the Character class. These extensions provide support for more Unicode properties. Each ICU release supports the latest version of Unicode available at that time.
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, Character.MAX_VALUE is still a char with the value U+FFFF, while the MAX_VALUE is an int with the value U+10FFFF.
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.
To use this class please add the jar file name icu4j.jar to the class path, since it contains data files which supply the information used by this file.
E.g. In Windows
set CLASSPATH=%CLASSPATH%;$JAR_FILE_PATH/ucharacter.jar.
Otherwise, another method would be to copy the files uprops.dat and unames.icu from the icu4j source subdirectory $ICU4J_SRC/src/com.ibm.icu.impl.data to your class directory $ICU4J_CLASS/com.ibm.icu.impl.data.
Aside from the additions for UTF-16 support, and the updated Unicode properties, the main differences between UCharacter and Character are:
- UCharacter is not designed to be a char wrapper and does not have APIs to which involves management of that single char.
  These include:
  - char charValue(),
  - int compareTo(java.lang.Character, java.lang.Character), etc.
- UCharacter does not include Character APIs that are deprecated, nor does it include the Java-specific character information, such as boolean isJavaIdentifierPart(char ch).
- 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.
Further detail on differences can be determined using the program com.ibm.icu.dev.test.lang.UCharacterCompare
In addition to Java compatibility functions, which calculate derived properties, this API provides low-level access to the Unicode Character Database.
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).
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:     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)
```
The C/POSIX character classes are also available in UnicodeSet patterns, using patterns like [:graph:] or \p{graph}.
[icu] Note: There are several ICU (and Java) whitespace functions. Comparison:
- 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)
- isWhitespace: Java isWhitespace; Z + whitespace ISO controls but excluding no-break spaces
- isSpaceChar: just Z (including no-break spaces)
This class is not subclassable.

- Method Detail
  - digit
```
public static int digit(int ch,
                        int radix)
```
    Returnss the numeric value of a decimal digit code point.
    This method observes the semantics of java.lang.Character.digit(). Note that this will return positive values for code points for which isDigit returns false, just like java.lang.Character.
    Semantic Change: In release 1.3.1 and prior, this did not treat the European letters as having a digit value, and also treated numeric letters and other numbers as digits. This has been changed to conform to the java semantics.
    A code point is a valid digit if and only if:
    - ch is a decimal digit or one of the european letters, and
    - the value of ch is less than the specified radix.
    Parameters:
    
    ch - the code point to query
    
    radix - the radix
    
    Returns:
    
    the numeric value represented by the code point in the specified radix, or -1 if the code point is not a decimal digit or if its value is too large for the radix
    
    Status:
    Stable ICU 2.1.
  - digit
```
public static int digit(int ch)
```
    Returnss the numeric value of a decimal digit code point.
    This is a convenience overload of digit(int, int) that provides a decimal radix.
    Semantic Change: In release 1.3.1 and prior, this treated numeric letters and other numbers as digits. This has been changed to conform to the java semantics.
    
    Parameters:
    
    ch - the code point to query
    
    Returns:
    
    the numeric value represented by the code point, or -1 if the code point is not a decimal digit or if its value is too large for a decimal radix
    
    Status:
    Stable ICU 2.1.
  - getNumericValue
```
public static int getNumericValue(int ch)
```
    Returns the numeric value of the code point as a nonnegative integer.
    If the code point does not have a numeric value, then -1 is returned.
    If the code point has a numeric value that cannot be represented as a nonnegative integer (for example, a fractional value), then -2 is returned.
    
    Parameters:
    
    ch - the code point to query
    
    Returns:
    
    the numeric value of the code point, or -1 if it has no numeric value, or -2 if it has a numeric value that cannot be represented as a nonnegative integer
    
    Status:
    Stable ICU 2.1.
  - getUnicodeNumericValue
```
public static double getUnicodeNumericValue(int ch)
```
    [icu] Returns the numeric value for a Unicode code point as defined in the Unicode Character Database.
    A "double" return type is necessary because some numeric values are fractions, negative, or too large for int.
    For characters without any numeric values in the Unicode Character Database, this function will return NO_NUMERIC_VALUE. Note: This is different from the Unicode Standard which specifies NaN as the default value.
    API Change: In release 2.2 and prior, this API has a return type int and returns -1 when the argument ch does not have a corresponding numeric value. This has been changed to synch with ICU4C This corresponds to the ICU4C function u_getNumericValue.
    
    Parameters:
    
    ch - Code point to get the numeric value for.
    
    Returns:
    
    numeric value of ch, or NO_NUMERIC_VALUE if none is defined.
    
    Status:
    Stable ICU 2.4.

  - getDirection
```
public static int getDirection(int ch)
```
    [icu] Returns the Bidirection property of a code point. For example, 0x0041 (letter A) has the LEFT_TO_RIGHT directional property.
    Result returned belongs to the interface UCharacterDirection

  - isMirrored
```
public static boolean isMirrored(int ch)
```
    Determines whether the code point has the "mirrored" property. This property is set for characters that are commonly used in Right-To-Left contexts and need to be displayed with a "mirrored" glyph.
    
    Parameters:
    
    ch - code point whose mirror is to be determined
    
    Returns:
    
    true if the code point has the "mirrored" property

  - getMirror
```
public static int getMirror(int ch)
```
    [icu] Maps the specified code point to a "mirror-image" code point. For code points with the "mirrored" property, implementations sometimes need a "poor man's" mapping to another code point such that the default glyph may serve as the mirror-image of the default glyph of the specified code point.
    This is useful for text conversion to and from codepages with visual order, and for displays without glyph selection capabilities.
    
    Parameters:
    
    ch - code point whose mirror is to be retrieved
    
    Returns:
    
    another code point that may serve as a mirror-image substitute, or ch itself if there is no such mapping or ch does not have the "mirrored" property
    
    Status:
    Stable ICU 2.1.
  - getBidiPairedBracket
```
public static int getBidiPairedBracket(int c)
```

    Parameters:
    
    c - the code point to be mapped
    
    Returns:
    
    the paired bracket code point, or c itself if there is no such mapping (Bidi_Paired_Bracket_Type=None)

```
    [icu] Return the Unicode name for a given property, as given in the Unicode database file PropertyAliases.txt. Most properties have more than one name. The nameChoice determines which one is returned. In addition, this function maps the property UProperty.GENERAL_CATEGORY_MASK to the synthetic names "gcm" / "General_Category_Mask". These names are not in PropertyAliases.txt.
    
    Parameters:
    
    property - UProperty selector.
    
    nameChoice - UProperty.NameChoice selector for which name to get. All properties have a long name. Most have a short name, but some do not. Unicode allows for additional names; if present these will be returned by UProperty.NameChoice.LONG + i, where i=1, 2,...
    
    Returns:
    
    a name, or null if Unicode explicitly defines no name ("n/a") for a given property/nameChoice. If a given nameChoice throws an exception, then all larger values of nameChoice will throw an exception.

```
    [icu] Return the Unicode name for a given property value, as given in the Unicode database file PropertyValueAliases.txt. Most values have more than one name. The nameChoice determines which one is returned. Note: Some of the names in PropertyValueAliases.txt can only be retrieved using UProperty.GENERAL_CATEGORY_MASK, not UProperty.GENERAL_CATEGORY. These include: "C" / "Other", "L" / "Letter", "LC" / "Cased_Letter", "M" / "Mark", "N" / "Number", "P" / "Punctuation", "S" / "Symbol", and "Z" / "Separator".
    
    Parameters:
    
    property - UProperty selector constant. UProperty.INT_START <= property < UProperty.INT_LIMIT or UProperty.BINARY_START <= property < UProperty.BINARY_LIMIT or UProperty.MASK_START < = property < UProperty.MASK_LIMIT. If out of range, null is returned.
    
    value - selector for a value for the given property. In general, valid values range from 0 up to some maximum. There are a few exceptions: (1.) UProperty.BLOCK values begin at the non-zero value BASIC_LATIN.getID(). (2.) UProperty.CANONICAL_COMBINING_CLASS values are not contiguous and range from 0..240. (3.) UProperty.GENERAL_CATEGORY_MASK values are mask values produced by left-shifting 1 by UCharacter.getType(). This allows grouped categories such as [:L:] to be represented. Mask values are non-contiguous.
    
    nameChoice - UProperty.NameChoice selector for which name to get. All values have a long name. Most have a short name, but some do not. Unicode allows for additional names; if present these will be returned by UProperty.NameChoice.LONG + i, where i=1, 2,...
    
    Returns:
    
    a name, or null if Unicode explicitly defines no name ("n/a") for a given property/value/nameChoice. If a given nameChoice throws an exception, then all larger values of nameChoice will throw an exception. If null is returned for a given nameChoice, then other nameChoice values may return non-null results.
    
    Throws:
    
    IllegalArgumentException - thrown if property, value, or nameChoice are invalid.

    locale - which string is to be converted in
    
    str - source string to be performed on
    
    titleIter - break iterator to determine the positions in which the character should be title cased.

                                 int options)
```
    Returns the titlecase version of the argument string.
    Position for titlecasing is determined by the argument break iterator, hence the user can customize his break iterator for a specialized titlecasing. In this case only the forward iteration needs to be implemented. If the break iterator passed in is null, the default Unicode algorithm will be used to determine the titlecase positions.
    Only positions returned by the break iterator will be title cased, character in between the positions will all be in lower case.

  - foldCase
```
public static int foldCase(int ch,
                           boolean defaultmapping)
```
    [icu] The given character is mapped to its case folding equivalent according to UnicodeData.txt and CaseFolding.txt; if the character has no case folding equivalent, the character itself is returned.
    This function only returns the simple, single-code point case mapping. Full case mappings should be used whenever possible because they produce better results by working on whole strings. They can map to a result string with a different length as appropriate. Full case mappings are applied by the case mapping functions that take String parameters rather than code points (int). See also the User Guide chapter on C/POSIX migration: https://unicode-org.github.io/icu/userguide/icu/posix#case-mappings
    
    Parameters:
    
    ch - the character to be converted
    
    defaultmapping - Indicates whether the default mappings defined in CaseFolding.txt are to be used, otherwise the mappings for dotted I and dotless i marked with 'T' in CaseFolding.txt are included.
    
    Returns:
    
    the case folding equivalent of the character, if any; otherwise the character itself.

    This API only gets the iterator for the modern, most up-to-date Unicode names. For older 1.0 Unicode names use get1_0NameIterator() or for extended names use getExtendedNameIterator().
    Example of use:
```
 ValueIterator iterator = UCharacter.getNameIterator();
 ValueIterator.Element element = new ValueIterator.Element();
 while (iterator.next(element)) {

```
    [icu] Check a binary Unicode property for a code point.
    Unicode, especially in version 3.2, defines many more properties than the original set in UnicodeData.txt.
    This API is intended to reflect Unicode properties as defined in the Unicode Character Database (UCD) and Unicode Technical Reports (UTR).
    For details about the properties see http://www.unicode.org/.
    For names of Unicode properties see the UCD file PropertyAliases.txt.
    This API does not check the validity of the codepoint.
    Important: If ICU is built with UCD files from Unicode versions below 3.2, then properties marked with "new" are not or not fully available.
    
    Parameters:
    
    ch - code point to test.
    
    property - selector constant from com.ibm.icu.lang.UProperty, identifies which binary property to check.
    
    Returns:
    
    true or false according to the binary Unicode property value for ch. Also false if property is out of bounds or if the Unicode version does not have data for the property at all, or not for this code point.
