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]” on page 48") 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.
