ICU4J (bundle named com.ibm.icu) provides advanced Unicode and Globalization support for software applications. The full version is included in the Eclipse SDK. For those that do not need that support and need a smaller footprint when building their own products, there is a subset of ICU4J, "com.ibm.icu.base" available from Orbit Downloads. [That subset used to be provided on this Eclipse download page but was removed to avoid unnecessary duplication (see bug 395003).]
