Language Support

The Solaris environment builds inherent internationalization features into every localized product. Localization facilities support the ANSI C recommendations for internationalization and localization that define the locale and related categories.

Locales

A locale contains the language with culturally specific information and conventions for a particular global region. Each process in the Solaris operating environment has the following set of locale attributes:

• Locale settings, which provide the locale and setlocale commands you use to list and set attributes before you start a process from the command line.

  For example, the Traditional Chinese locales and the English/ASCII locale both have a category that defines the display of time and date according to the cultural format, as well as the actual Traditional Chinese or English/ASCII characters for the time and date.

• Codesets, which support coding conventions for the CNS11643 and BIG5 character sets. These sets enable you to input, display, and print Traditional Chinese text in file names, system messages, and terminal (TTY), email, and data file content.

• htt input method server, which handles Traditional Chinese input for the Solaris operating environment. The htt server receives your keyboard input and converts it to Traditional Chinese characters that are used in Traditional Chinese applications.

Traditional Chinese Locales

The Traditional Chinese Solaris operating environment provides simultaneous support for the locales in the following table. The locales look the same to the end user, but the internal character encoding is different.

Input Method Auxiliary Window

The input method auxiliary window supports the following new functions:

• Input method switching

• Input methods properties configuration

• Lookup tables for the following character sets:

  • HKSCS

  • CNS11643

  • BIG5

  • Unicode

• User defined characters

Locale Categories

In the Traditional Chinese Solaris 9 operating environment, you can use the following general and specific categories as defined by ANSI C for the Traditional Chinese and English locales.

• General LC_ALL setting that invokes all of the categories for locale-related aspects of the environment.

• Specific settings for particular aspects of the environment which include:

  • LC_CTYPE

  • LC_TIME

  • LC_NUMERIC

  • LC_MONETARY

  • LC_COLLATE

  • LC_MESSAGES

For example, the Traditional Chinese and the English/ASCII locales have the LC_TIME category that defines the display of the time and date according to the cultural format, as well as the actual Traditional Chinese or English/ASCII characters used in the display.
