|

<li>All properties and algorithms are upgraded to <a href="http://www.unicode.org/reports/tr28/">Unicode

3.2</a>.
|
||||
<li>The UCA (<a href="http://www.unicode.org/reports/tr10/">Unicode
|
||||
Collation Algorithm</a>) table is updated to the current version 3.1.1,
|
||||
with Unicode 3.2-based canonical closure.
|
||||
<li>Most Unicode properties are now <a href="http://oss.software.ibm.com/cvs/icu/~checkout~/icuhtml/design/ucd_icu.html">available

|

</ul>
|
||||
|
||||
<p><b>Enhancements from Release 2.1 (partial list)</b></p>
|
||||
</li>
|
||||
<li><b>Collation</b><br>
|
||||
The collation engine has been completely rewritten to be conformant to the
|
||||
latest version of the UCA, and to use the same performance enhancements
|
||||
available in ICU4C. Compared to the JDK, it is dramatically faster, has much
|
||||
smaller sort keys, more customization, and better and additional
|
||||
locale-specific data. For more details, see <a href="#collation">Collation
|
||||
Enhancements</a> below.
|
||||
<li><b>Normalization</b><br>
|
||||
The Normalization service adds several high performance functions for:

<li><a name="2.1changes">Changes for JDK 1.4</a>

||||
<ul>

<li><a href="#ResourceData">ICU Resource Data added to ICU4J</a></li>
|
||||
<li>ICU4J size increase because of new resource data, clients can trim
|
||||
</ul>
|
||||
<li>fast concatenation, preserving NFC and NFD.
|
||||
<li>fast detection of normalized text
|
||||
<li>fast canonical equivalance and/or case-insensitive matching</li>
|
||||
</ul>
|
||||
<li><b>Transliteration</b><br>
|
||||
There are now transliterators for all scripts used by ICU locales. In
|
||||
addition, mixed-script text can be automatically transliterated to a target
|
||||
script.
|
||||
<li><b>Alternate currency formatting</b><br>
|
||||
ICU permits arbitrary currencies to be formatted for display according to
|
||||
arbitrary locales, such as formatting Yen amounts for the US.
|
||||
<li><b>UnicodeSets</b><br>
|
||||
UnicodeSets now permit strings as well as characters, so that they can
|
||||
contain grapheme-clusters. UnicodeSetIterator provides a fast mechanism for
|
||||
iterating through the contents (code points and strings) of a UnicodeSet.
|
||||
For code points the iteration is either by individual code point or by
|
||||
ranges.
|
||||
<li><b>General improvements</b><br>
|
||||
Performance has been enhanced in a number of services, and a number of
|
||||
significant bugs have been fixed.</li>
