-/**
- *
- * A MessageFormat produces concatenated messages in a
- * language-neutral way.  It should be used for all string
- * concatenations that are visible to end users.
- * <P>
- * A MessageFormat contains an array of <EM>subformats</EM> arranged
- * within a <EM>template string</EM>.  Together, the subformats and
- * template string determine how the MessageFormat will operate during
- * formatting and parsing.
- * <P>
- * Typically, both the subformats and the template string are
- * specified at once in a <EM>pattern</EM>.  By using different
- * patterns for different locales, messages may be localized.
- * <P>
- * During formatting, the MessageFormat takes an array of arguments
- * and produces a user-readable string.  Each argument is a
- * Formattable object; they may be passed in in an array, or as a
- * single Formattable object which itself contains an array.  Each
- * argument is matched up with its corresponding subformat, which then
- * formats it into a string.  The resultant strings are then assembled
- * within the string template of the MessageFormat to produce the
- * final output string.
- * <p>
- * <strong>Note:</strong>
- * In ICU 4.0 MessageFormat supports named arguments.  If a named argument
- * is used, all arguments must be named.  Names start with a character in 
- * <code>UCHAR_ID_START</code> and continue with characters in 
- * <code>UCHARID_CONTINUE</code>, in particular they do not start with a digit.
- * If named arguments are used, {@link #usesNamedArguments()} will return true.
- * <p>
- * The other new methods supporting named arguments are 
- * {@link #getFormatNames(UErrorCode& status)},
- * {@link #getFormat(const UnicodeString& formatName, UErrorCode& status)}
- * {@link #setFormat(const UnicodeString& formatName, const Format& format, UErrorCode& status)},
- * {@link #adoptFormat(const UnicodeString& formatName, Format* formatToAdopt, UErrorCode& status)},
- * {@link #format(const Formattable* arguments, const UnicodeString *argumentNames, int32_t cnt, UnicodeString& appendTo, FieldPosition& status, int32_t recursionProtection, UErrorCode& success)},
- * {@link #format(const UnicodeString* argumentNames, const Formattable* arguments, int32_t count, UnicodeString& appendTo,UErrorCode& status)}.
- * These methods are all compatible with patterns that do not used named arguments-- 
- * in these cases the keys in the input or output use <code>UnicodeString</code>s 
- * that name the argument indices, e.g. "0", "1", "2"... etc.
- * <p>
- * When named arguments are used, certain methods on MessageFormat that take or
- * return arrays do not perform any action, since it is not possible to
- * identify positions in an array using a name.  UErrorCode is set to
- * U_ARGUMENT_TYPE_MISMATCH if there is a status/success field in the method.
- * These methods are 
- * {@link #adoptFormats(Format** newFormats, int32_t count)},
- * {@link #setFormats(const Format** newFormats,int32_t count)},
- * {@link #adoptFormat(int32_t n, Format *newFormat)},
- * {@link #getFormats(int32_t& cnt)},
- * {@link #format(const Formattable* source,int32_t cnt,UnicodeString& appendTo, FieldPosition& ignore, UErrorCode& success)},
- * {@link #format(const UnicodeString& pattern,const Formattable* arguments,int32_t cnt,UnicodeString& appendTo,UErrorCode& success)},
- * {@link #format(const Formattable& source, UnicodeString& appendTo,FieldPosition& ignore, UErrorCode& success)},
- * {@link #format(const Formattable* arguments, int32_t cnt, UnicodeString& appendTo, FieldPosition& status, int32_t recursionProtection,UErrorCode& success)},
- * {@link #parse(const UnicodeString& source, ParsePosition& pos,int32_t& count)},
- * {@link #parse(const UnicodeString& source, int32_t& cnt, UErrorCode& status)}
- * <p>
- *
- * <P>
- * During parsing, an input string is matched against the string
- * template of the MessageFormat to produce an array of Formattable
- * objects.  Plain text of the template string is matched directly
- * against intput text.  At each position in the template string where
- * a subformat is located, the subformat is called to parse the
- * corresponding segment of input text to produce an output argument.
- * In this way, an array of arguments is created which together
- * constitute the parse result.
- * <P>
- * Parsing may fail or produce unexpected results in a number of
- * circumstances.
- * <UL>
- * <LI>If one of the arguments does not occur in the pattern, it
- * will be returned as a default Formattable.
- * <LI>If the format of an argument is loses information, such as with
- * a choice format where a large number formats to "many", then the
- * parse may not correspond to the originally formatted argument.
- * <LI>MessageFormat does not handle ChoiceFormat recursion during
- * parsing; such parses will fail.
- * <LI>Parsing will not always find a match (or the correct match) if
- * some part of the parse is ambiguous.  For example, if the pattern
- * "{1},{2}" is used with the string arguments {"a,b", "c"}, it will
- * format as "a,b,c".  When the result is parsed, it will return {"a",
- * "b,c"}.
- * <LI>If a single argument is formatted more than once in the string,
- * then the rightmost subformat in the pattern string will produce the
- * parse result; prior subformats with the same argument index will
- * have no effect.
- * </UL>
- * Here are some examples of usage:
- * <P>
- * Example 1:
- * <pre>
- * \code
- *     UErrorCode success = U_ZERO_ERROR;
- *     GregorianCalendar cal(success);
- *     Formattable arguments[] = {
- *         7L,
- *         Formattable( (Date) cal.getTime(success), Formattable::kIsDate),
- *         "a disturbance in the Force"
- *     };
- *
- *     UnicodeString result;
- *     MessageFormat::format(
- *          "At {1,time} on {1,date}, there was {2} on planet {0,number}.",
- *          arguments, 3, result, success );
- *
- *     cout << "result: " << result << endl;
- *     //<output>: At 4:34:20 PM on 23-Mar-98, there was a disturbance
- *     //             in the Force on planet 7.
- * \endcode
- * </pre>
- * Typically, the message format will come from resources, and the
- * arguments will be dynamically set at runtime.
- * <P>
- * Example 2:
- * <pre>
- *  \code
- *     success = U_ZERO_ERROR;
- *     Formattable testArgs[] = {3L, "MyDisk"};
- *
- *     MessageFormat form(
- *         "The disk \"{1}\" contains {0} file(s).", success );
- *
- *     UnicodeString string;
- *     FieldPosition fpos = 0;
- *     cout << "format: " << form.format(testArgs, 2, string, fpos, success ) << endl;
- *
- *     // output, with different testArgs:
- *     // output: The disk "MyDisk" contains 0 file(s).
- *     // output: The disk "MyDisk" contains 1 file(s).
- *     // output: The disk "MyDisk" contains 1,273 file(s).
- *  \endcode
- *  </pre>
- *
- *  The pattern is of the following form.  Legend:
- *  <pre>
- * \code
- *       {optional item}
- *       (group that may be repeated)*
- * \endcode
- *  </pre>
- *  Do not confuse optional items with items inside quotes braces, such
- *  as this: "{".  Quoted braces are literals.
- *  <pre>
- *  \code
- *       messageFormatPattern := string ( "{" messageFormatElement "}" string )*
- *
- *       messageFormatElement := argumentIndex | argumentName { "," elementFormat }
- *
- *       elementFormat := "time" { "," datetimeStyle }
- *                      | "date" { "," datetimeStyle }
- *                      | "number" { "," numberStyle }
- *                      | "choice" "," choiceStyle
- *
- *       datetimeStyle := "short"
- *                      | "medium"
- *                      | "long"
- *                      | "full"
- *                      | dateFormatPattern
- *
- *       numberStyle :=   "currency"
- *                      | "percent"
- *                      | "integer"
- *                      | numberFormatPattern
- *
- *       choiceStyle :=   choiceFormatPattern
- * 
- *       pluralStyle := pluralFormatPattern
- * \endcode
- * </pre>
- * If there is no elementFormat, then the argument must be a string,
- * which is substituted. If there is no dateTimeStyle or numberStyle,
- * then the default format is used (e.g.  NumberFormat::createInstance(),
- * DateFormat::createTimeInstance(DateFormat::kDefault, ...) or DateFormat::createDateInstance(DateFormat::kDefault, ...). For
- * a ChoiceFormat, the pattern must always be specified, since there
- * is no default.
- * <P>
- * In strings, single quotes can be used to quote syntax characters.
- * A literal single quote is represented by '', both within and outside
- * of single-quoted segments.  Inside a
- * messageFormatElement, quotes are <EM>not</EM> removed. For example,
- * {1,number,$'#',##} will produce a number format with the pound-sign
- * quoted, with a result such as: "$#31,45".
- * <P>
- * If a pattern is used, then unquoted braces in the pattern, if any,
- * must match: that is, "ab {0} de" and "ab '}' de" are ok, but "ab
- * {0'}' de" and "ab } de" are not.
- * <p>
- * <dl><dt><b>Warning:</b><dd>The rules for using quotes within message
- * format patterns unfortunately have shown to be somewhat confusing.
- * In particular, it isn't always obvious to localizers whether single
- * quotes need to be doubled or not. Make sure to inform localizers about
- * the rules, and tell them (for example, by using comments in resource
- * bundle source files) which strings will be processed by MessageFormat.
- * Note that localizers may need to use single quotes in translated
- * strings where the original version doesn't have them.
- * <br>Note also that the simplest way to avoid the problem is to
- * use the real apostrophe (single quote) character U+2019 (') for
- * human-readable text, and to use the ASCII apostrophe (U+0027 ' )
- * only in program syntax, like quoting in MessageFormat.
- * See the annotations for U+0027 Apostrophe in The Unicode Standard.</p>
- * </dl>
- * <P>
- * The argumentIndex is a non-negative integer, which corresponds to the
- * index of the arguments presented in an array to be formatted.  The
- * first argument has argumentIndex 0.
- * <P>
- * It is acceptable to have unused arguments in the array.  With missing
- * arguments or arguments that are not of the right class for the
- * specified format, a failing UErrorCode result is set.
- * <P>
- * For more sophisticated patterns, you can use a ChoiceFormat to get
- * output:
- * <pre>
- * \code
- *     UErrorCode success = U_ZERO_ERROR;
- *     MessageFormat* form("The disk \"{1}\" contains {0}.", success);
- *     double filelimits[] = {0,1,2};
- *     UnicodeString filepart[] = {"no files","one file","{0,number} files"};
- *     ChoiceFormat* fileform = new ChoiceFormat(filelimits, filepart, 3);
- *     form.setFormat(1, *fileform); // NOT zero, see below
- *
- *     Formattable testArgs[] = {1273L, "MyDisk"};
- *
- *     UnicodeString string;
- *     FieldPosition fpos = 0;
- *     cout << form.format(testArgs, 2, string, fpos, success) << endl;
- *
- *     // output, with different testArgs
- *     // output: The disk "MyDisk" contains no files.
- *     // output: The disk "MyDisk" contains one file.
- *     // output: The disk "MyDisk" contains 1,273 files.
- * \endcode
- * </pre>
- * You can either do this programmatically, as in the above example,
- * or by using a pattern (see ChoiceFormat for more information) as in:
- * <pre>
- * \code
- *    form.applyPattern(
- *      "There {0,choice,0#are no files|1#is one file|1<are {0,number,integer} files}.");
- * \endcode
- * </pre>
- * <P>
- * <EM>Note:</EM> As we see above, the string produced by a ChoiceFormat in
- * MessageFormat is treated specially; occurences of '{' are used to
- * indicated subformats, and cause recursion.  If you create both a
- * MessageFormat and ChoiceFormat programmatically (instead of using
- * the string patterns), then be careful not to produce a format that
- * recurses on itself, which will cause an infinite loop.
- * <P>
- * <EM>Note:</EM> Subformats are numbered by their order in the pattern.
- * This is <EM>not</EM> the same as the argumentIndex.
- * <pre>
- * \code
- *    For example: with "abc{2}def{3}ghi{0}...",
- *
- *    format0 affects the first variable {2}
- *    format1 affects the second variable {3}
- *    format2 affects the second variable {0}
- * \endcode
- * </pre>
- *
- * <p><em>User subclasses are not supported.</em> While clients may write
- * subclasses, such code will not necessarily work and will not be
- * guaranteed to work stably from release to release.

-/**
- * The Normalizer class supports the standard normalization forms described in
- * <a href="http://www.unicode.org/unicode/reports/tr15/" target="unicode">
- * Unicode Standard Annex #15: Unicode Normalization Forms</a>.
- *
- * The Normalizer class consists of two parts:
- * - static functions that normalize strings or test if strings are normalized
- * - a Normalizer object is an iterator that takes any kind of text and
- *   provides iteration over its normalized form
- *
- * The Normalizer class is not suitable for subclassing.
- *
- * The static functions are basically wrappers around the C implementation,
- * using UnicodeString instead of UChar*.
- * For basic information about normalization forms and details about the C API
- * please see the documentation in unorm.h.
- *
- * The iterator API with the Normalizer constructors and the non-static functions
- * uses a CharacterIterator as input. It is possible to pass a string which
- * is then internally wrapped in a CharacterIterator.
- * The input text is not normalized all at once, but incrementally where needed
- * (providing efficient random access).
- * This allows to pass in a large text but spend only a small amount of time
- * normalizing a small part of that text.
- * However, if the entire text is normalized, then the iterator will be
- * slower than normalizing the entire text at once and iterating over the result.
- * A possible use of the Normalizer iterator is also to report an index into the
- * original text that is close to where the normalized characters come from.
- *
- * <em>Important:</em> The iterator API was cleaned up significantly for ICU 2.0.
- * The earlier implementation reported the getIndex() inconsistently,
- * and previous() could not be used after setIndex(), next(), first(), and current().
- *
- * Normalizer allows to start normalizing from anywhere in the input text by
- * calling setIndexOnly(), first(), or last().
- * Without calling any of these, the iterator will start at the beginning of the text.
- *
- * At any time, next() returns the next normalized code point (UChar32),
- * with post-increment semantics (like CharacterIterator::next32PostInc()).
- * previous() returns the previous normalized code point (UChar32),
- * with pre-decrement semantics (like CharacterIterator::previous32()).
- *
- * current() returns the current code point
- * (respectively the one at the newly set index) without moving
- * the getIndex(). Note that if the text at the current position
- * needs to be normalized, then these functions will do that.
- * (This is why current() is not const.)
- * It is more efficient to call setIndexOnly() instead, which does not
- * normalize.
- *
- * getIndex() always refers to the position in the input text where the normalized
- * code points are returned from. It does not always change with each returned
- * code point.
- * The code point that is returned from any of the functions
- * corresponds to text at or after getIndex(), according to the
- * function's iteration semantics (post-increment or pre-decrement).
- *
- * next() returns a code point from at or after the getIndex()
- * from before the next() call. After the next() call, the getIndex()
- * might have moved to where the next code point will be returned from
- * (from a next() or current() call).
- * This is semantically equivalent to array access with array[index++]
- * (post-increment semantics).
- *
- * previous() returns a code point from at or after the getIndex()
- * from after the previous() call.
- * This is semantically equivalent to array access with array[--index]
- * (pre-decrement semantics).
- *
- * Internally, the Normalizer iterator normalizes a small piece of text
- * starting at the getIndex() and ending at a following "safe" index.
- * The normalized results is stored in an internal string buffer, and
- * the code points are iterated from there.
- * With multiple iteration calls, this is repeated until the next piece
- * of text needs to be normalized, and the getIndex() needs to be moved.
- *
- * The following "safe" index, the internal buffer, and the secondary
- * iteration index into that buffer are not exposed on the API.
- * This also means that it is currently not practical to return to
- * a particular, arbitrary position in the text because one would need to
- * know, and be able to set, in addition to the getIndex(), at least also the
- * current index into the internal buffer.
- * It is currently only possible to observe when getIndex() changes
- * (with careful consideration of the iteration semantics),
- * at which time the internal index will be 0.
- * For example, if getIndex() is different after next() than before it,
- * then the internal index is 0 and one can return to this getIndex()
- * later with setIndexOnly().
