BreakIterator C API

- * - * 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 - * . 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. - *
