The J2RE for Windows currently is offered in two bundles: US-only and International. The international J2RE has the additional files lib/charsets.jar and lib/ext/localedata.jar, which provide support for non-US locales. The difference in download size is about 2.5 MB.

A better split would be one bundle supporting Western European languages (adding ISO 8859-15 character converters and all locale data for Catalan, Danish, Dutch, English, Finnish, French, German, Icelandic, Italian, Norwegian, Portuguese, Spanish, and Swedish to the current US bundle) and one complete International bundle. This would add about 47 KB after crunching and compression to the smaller bundle, but would spare customers in Western Europe and Latin America the download of another 2.5 MB.
