- * \brief C API: Collator |
- * |
- * <h2> Collator C API </h2> |
- * |
- * The C API for Collator performs locale-sensitive |
- * string comparison. You use this service to build |
- * searching and sorting routines for natural language text. |
- * <em>Important: </em>The ICU collation service has been reimplemented |
- * in order to achieve better performance and UCA compliance. |
- * For details, see the |
- * <a href="http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm"> |
- * collation design document</a>. |
- * <p> |
- * For more information about the collation service see |
- * <a href="http://icu-project.org/userguide/Collate_Intro.html">the users guide</a>. |
- * <p> |
- * Collation service provides correct sorting orders for most locales supported in ICU. |
- * If specific data for a locale is not available, the orders eventually falls back |
- * to the <a href="http://www.unicode.org/unicode/reports/tr10/">UCA sort order</a>. |
- * <p> |
- * Sort ordering may be customized by providing your own set of rules. For more on |
- * this subject see the |
- * <a href="http://icu-project.org/userguide/Collate_Customization.html"> |
- * Collation customization</a> section of the users guide. |
