<p>The C API for <a class="el" href="classCollator.html" title="The Collator class performs locale-sensitive string comparison.">Collator</a> 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>
<p>For more information about the collation service see <a href="http://icu-project.org/userguide/Collate_Intro.html">the users guide</a>. </p>
<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>
<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. </p>

<p>The strength attribute. </p>
<p>Can be either UCOL_PRIMARY, UCOL_SECONDARY, UCOL_TERTIARY, UCOL_QUATERNARY or UCOL_IDENTICAL. The usual strength for most locales (except Japanese) is tertiary. Quaternary strength is useful when combined with shifted setting for alternate handling attribute and for JIS x 4061 collation, when it is used to distinguish between Katakana and Hiragana (this is achieved by setting the UCOL_HIRAGANA_QUATERNARY mode to on. Otherwise, quaternary level is affected only by the number of non ignorable code points in the string. Identical strength is rarely useful, as it amounts to codepoints of the NFD form of the string. </p>

<p>Produce a bound for a given sortkey and a number of levels. </p>
<p>Return value is always the number of bytes needed, regardless of whether the result buffer was big enough or even valid.<br/>
Resulting bounds can be used to produce a range of strings that are between upper and lower bounds. For example, if bounds are produced for a sortkey of string "smith", strings between upper and lower bounds with one level would include "Smith", "SMITH", "sMiTh".<br/>
There are two upper bounds that can be produced. If UCOL_BOUND_UPPER is produced, strings matched would be as above. However, if bound produced using UCOL_BOUND_UPPER_LONG is used, the above example will also match "Smithsonian" and similar.<br/>
For more on usage, see example in cintltst/capitst.c in procedure TestBounds. Sort keys may be compared using <code>strcmp</code>. </p>

<p>If two locales return the same result, then collators instantiated for these locales will behave equivalently.

The return result has no other meaning than that stated above, and implies nothing as to the relationship between the two locales. This is intended for use by applications who wish to cache collators, or otherwise reuse collators when possible. The functional equivalent may change over time.
