Overview of the International Components for Unicode (ICU) library

The International Components for Unicode (ICU) library is an open source project that provides support for Unicode and software globalization. PolicyCenter includes this library in the base configuration.

The ICU library, icu4j, attempts to maintain API compatibility with the standard Java JDK. However, for most features, the ICU library provides significant performance improvements and a richer feature set than the Java JDK. The core of the ICU library is the Common Locale Data Repository (CLDR). The CLDR repository is a comprehensive repository of locale data.
