Unicode supplementary character support (JSR-204)

    Description

      Support Unicode "supplementary characters" (as defined in http://www.unicode.org/glossary/) throughout the J2SE platform. This affects APIs and implementations for character properties, I/O, font rendering, and other areas. Supplementary characters cannot be handled by the existing APIs accepting or returning single 16-bit char values, so a new approach is necessary.

      Once support for supplementary characters is defined, the Java platform can be upgraded to support the latest Unicode version (RFE 4640853).
