Process Code Format

The process code format, which is also known as wide-character code format in the Solaris 9 product, is private and subject to change in a future release. Therefore, when developing an international application, do not assume the process code format is the same. Instead, use the internationalization APIs in libc described in Internationalization APIs in libc.

The process code for all Unicode locales is in UTF-32 representation. For more detail on UTF-32, refer to the “Unicode Standard Annex #19: UTF 32” and “Unicode Standard Annex #27: Unicode 3.1” from The Unicode Consortium or http://www.unicode.org/.
