Unicode 3.0 Support [11i v2]

Summary of Change

HP-UX 11i v2 includes Unicode 3.0 support, which is an extension to the previously supported Unicode 2.1 standard.

Unicode 3.0 is aligned with the revised ISO 10646-1:2000 standard and includes an additional 10,194 characters from the previous version of the standard. Most notable of these additional characters are 6,582 new CJK characters (Han Extension A) for use in various Asian countries.

All 34 previously supported system supplied utf8 locales have been updated to support the character repertoire specified by the Unicode 3.0 standard. In addition, all new utf8 locales (see “New Latin and South American Locales [11i v2]”") align with the Unicode 3.0 standard.

Changes have been made in the Streams ldterm modules, libc utf8 methods libraries, Xlib, and Asian print drivers to support Unicode 3.0.

Impact to the Customer

Base offering (installed on all systems): Approximately 1 MB additional disk space is required. No additional memory requirements are needed when running in any of these locales.

Compatibility

There are no compatibility issues involved with the addition of this feature.

Performance

There is no impact to performance.

Machines Affected or No Longer Supported

Support for Unicode 3.0 is only provided for PA-RISC 1.1 and 2.0 (32/64 bit modes) as well as Itanium 32/64 bit applications. Unicode 3.0 support is not provided for applications that were compiled on HP-UX 10.20 systems. Applications compiled with HP-UX 10.20 will continue to use the Unicode 2.1 character repertoire as supported in earlier HP-UX releases.

Future Plans

Support for subsequent versions of the Unicode Standard is planned in forthcoming releases.
