In the Solaris Express 8/04 release, Unicode 4.0-based supplementary characters are supported in J2SE 5.
Developers can now use Unicode-based supplementary characters, represented as pairs of Java characters, with the Java language. When using the string-based and text-based APIs, no additional effort is required.
For further information, see http://java.sun.com/j2se/1.5.0/docs/.
Previously, Unicode 3.2 support was available in the Software Express pilot program. For Solaris 9 users, Unicode 3.2 support is new in the Solaris 9 8/03 release.
