-/**
- * 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>.
- *
- * Note: This API has been replaced by the Normalizer2 class and is only available
- * for backward compatibility. This class simply delegates to the Normalizer2 class.
- * There is one exception: The new API does not provide a replacement for Normalizer::compare().
- *
- * 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.
- *
- * 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
- * use 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().
- *
- * Note: While the setIndex() and getIndex() refer to indices in the
- * underlying Unicode input text, the next() and previous() methods
- * iterate through characters in the normalized output.
- * This means that there is not necessarily a one-to-one correspondence
- * between characters returned by next() and previous() and the indices
- * passed to and returned from setIndex() and getIndex().
- * It is for this reason that Normalizer does not implement the CharacterIterator interface.
