The International Components for Unicode (ICU), option 39, is a C and C++
|
||
|
|
library that provides Unicode services for writing global applications in ILE
|
||
|
|
programming languages. ICU offers flexibility to extend and customize the supplied services, which
|
||
|
|
include:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li><strong>Text:</strong> Unicode text handling, full character properties and
|
||
|
|
character set conversions (500+ codepages)</li>
|
||
|
|
|
||
|
|
<li><strong>Analysis:</strong> Unicode regular expressions; full Unicode sets;
|
||
|
|
character, word and line boundaries</li>
|
||
|
|
|
||
|
|
<li><strong>Comparison:</strong> Language sensitive collation and
|
||
|
|
searching</li>
|
||
|
|
|
||
|
|
<li><strong>Transformations:</strong> normalization, upper/lowercase, script
|
||
|
|
transliterations (50+ pairs)</li>
|
||
|
|
|
||
|
|
<li><strong>Locales:</strong> Comprehensive locale data (230+) and resource
|
||
|
|
bundle architecture</li>
|
||
|
|
|
||
|
|
<li><strong>Complex Text Layout:</strong> Arabic, Hebrew, Indic and Thai</li>
|
||
|
|
|
||
|
|
<li><strong>Time:</strong> Multi-calendar and time zone</li>
|
||
|
|
|
||
|
|
<li><strong>Formatting and Parsing:</strong> dates, times, numbers, currencies,
|
||
|
|
messages, and rule-based</li>
|
||
|
|
</ul>

<p>ICU is an open source development project sponsored, supported, and used by
|
||
|
|
IBM<SUP>(R)</SUP>. ICU provides over 200 APIs that you can use to process Unicode data in
|
||
|
|
your ILE application. See the <a href="#xmp1">RPG example</a> and <a href=
