37 * \brief C API: BreakIterator
38 *
39 * <h2> BreakIterator C API </h2>
40 *
41 * The BreakIterator C API defines methods for finding the location
42 * of boundaries in text. Pointer to a UBreakIterator maintain a
43 * current position and scan over text returning the index of characters
44 * where boundaries occur.
45 * <p>
46 * Line boundary analysis determines where a text string can be broken
47 * when line-wrapping. The mechanism correctly handles punctuation and
48 * hyphenated words.
49 * <p>
50 * Note: The locale keyword "lb" can be used to modify line break
51 * behavior according to the CSS level 3 line-break options, see
52 * <http://dev.w3.org/csswg/css-text/#line-breaking>. For example:
53 * "ja@lb=strict", "zh@lb=loose".
54 * <p>
55 * Sentence boundary analysis allows selection with correct
56 * interpretation of periods within numbers and abbreviations, and
57 * trailing punctuation marks such as quotation marks and parentheses.
58 * <p>
59 * Note: The locale keyword "ss" can be used to enable use of
60 * segmentation suppression data (preventing breaks in English after
61 * abbreviations such as "Mr." or "Est.", for example), as follows:
62 * "en@ss=standard".
63 * <p>
64 * Word boundary analysis is used by search and replace functions, as
65 * well as within text editing applications that allow the user to
66 * select words with a double click. Word selection provides correct
67 * interpretation of punctuation marks within and following
68 * words. Characters that are not part of a word, such as symbols or
69 * punctuation marks, have word-breaks on both sides.
70 * <p>
71 * Character boundary analysis identifies the boundaries of
72 * "Extended Grapheme Clusters", which are groupings of codepoints
73 * that should be treated as character-like units for many text operations.
74 * Please see Unicode Standard Annex #29, Unicode Text Segmentation,
75 * http://www.unicode.org/reports/tr29/ for additional information
76 * on grapheme clusters and guidelines on their use.
77 * <p>
78 * Title boundary analysis locates all positions,
79 * typically starts of words, that should be set to Title Case
80 * when title casing the text.
81 * <p>
82 * The text boundary positions are found according to the rules
83 * described in Unicode Standard Annex #29, Text Boundaries, and
84 * Unicode Standard Annex #14, Line Breaking Properties. These
85 * are available at http://www.unicode.org/reports/tr14/ and
86 * http://www.unicode.org/reports/tr29/.
87 * <p>
88 * In addition to the plain C API defined in this header file, an
89 * object oriented C++ API with equivalent functionality is defined in the
90 * file brkiter.h.
91 * <p>
92 * Code snippets illustrating the use of the Break Iterator APIs
93 * are available in the ICU User Guide,
94 * http://icu-project.org/userguide/boundaryAnalysis.html
95 * and in the sample program icu/source/samples/break/break.cpp
