How To Install icu4j on Fedora 34
Introduction
In this tutorial we learn how to install icu4j on Fedora 34.
What is icu4j
The International Components for Unicode (ICU) library provides robust and full-featured Unicode services on a wide variety of platforms. ICU supports the most current version of the Unicode standard, and provides support for supplementary characters (needed for GB 18030 repertoire support). Java provides a very strong foundation for global programs, and IBM and the ICU team played a key role in providing globalization technology into Sun’s Java. But because of its long release schedule, Java cannot always keep up-to-date with evolving standards. The ICU team continues to extend Java’s Unicode and internationalization support, focusing on improving performance, keeping current with the Unicode standard, and providing richer APIs, while remaining as compatible as possible with the original Java text and internationalization API design.
