3 Locales

The Compaq Tru64 UNIX operating system supports different Chinese locales for different countries and areas. These include Taiwan, People's Republic of China (PRC), and Hong Kong. Table 3-1 shows the valid Chinese locales with different countries, codesets, and collating sequences.

Note

zh_TW is an alias of zh_TW.eucTW, and zh_CN is an alias of zh_CN.dechanzi.

UTF-8	zh_CN.UTF-8 zh_TW.UTF-8 zh_HK.UTF-8	zh_CN.GBK zh_TW.dechanyu zh_HK.dechanyu

Locales that support the same country and codeset are basically the same. The radical, stroke, pinyin, and chuyin modifiers after the at (@) sign specify different criterion for collation and sorting. Moreover, the characters defined in character set standards have collating precedence over user-defined characters, which, in turn, have precedence over undefined or reserved characters.

The ucs4 modifier indicates that UCS-4 is used as the internal processing code. The classification information, however, is not provided for the full set of UCS-4 characters, but only for the corresponding language.

If you are using DECwindows Motif, you can select the locale through the Language Menu of Session Manager. If you are using CDE, you can select the locale using the language menu on the CDE login screen. The applicable locales are shown in Table 3-1.
