 * \file
 * \brief C API: BreakIterator
 *
 * <h2> BreakIterator C API </h2>
 *
 * The BreakIterator C API defines methods for finding the location
 * of boundaries in text. Pointer to a UBreakIterator maintain a
 * current position and scan over text returning the index of characters
 * where boundaries occur.
 * 
 * Line boundary analysis determines where a text string can be broken
 * when line-wrapping. The mechanism correctly handles punctuation and
 * hyphenated words.
 * 
 * Note: The locale keyword "lb" can be used to modify line break
 * behavior according to the CSS level 3 line-break options, see
 * <http://dev.w3.org/csswg/css-text/#line-breaking>. For example:
 * "ja@lb=strict", "zh@lb=loose".
 * 
 * Sentence boundary analysis allows selection with correct
 * interpretation of periods within numbers and abbreviations, and
 * trailing punctuation marks such as quotation marks and parentheses.
 * 
 * Note: The locale keyword "ss" can be used to enable use of
 * segmentation suppression data (preventing breaks in English after
 * abbreviations such as "Mr." or "Est.", for example), as follows:
 * "en@ss=standard".
 * 
 * Word boundary analysis is used by search and replace functions, as
 * well as within text editing applications that allow the user to
 * select words with a double click. Word selection provides correct
 * interpretation of punctuation marks within and following
 * words. Characters that are not part of a word, such as symbols or
 * punctuation marks, have word-breaks on both sides.
 * 
 * Character boundary analysis identifies the boundaries of
 * "Extended Grapheme Clusters", which are groupings of codepoints
 * that should be treated as character-like units for many text operations.
 * Please see Unicode Standard Annex #29, Unicode Text Segmentation,
 * http://www.unicode.org/reports/tr29/ for additional information
 * on grapheme clusters and guidelines on their use.
 * 
 * Title boundary analysis locates all positions,
 * typically starts of words, that should be set to Title Case
 * when title casing the text.
 * 
 * The text boundary positions are found according to the rules
 * described in Unicode Standard Annex #29, Text Boundaries, and
 * Unicode Standard Annex #14, Line Breaking Properties. These
 * are available at http://www.unicode.org/reports/tr14/ and
 * http://www.unicode.org/reports/tr29/.
 * 
 * In addition to the plain C API defined in this header file, an
 * object oriented C++ API with equivalent functionality is defined in the
 * file brkiter.h.
 * 
 * Code snippets illustrating the use of the Break Iterator APIs
 * are available in the ICU User Guide,
 * http://icu-project.org/userguide/boundaryAnalysis.html
 * and in the sample program icu/source/samples/break/break.cpp
