Locale
簡單說就是一組「地區語言」的資訊。它包括了
LC_CTYPE: 字符定義
LC_MESSAGES: 訊息顯示
LC_TIME: 時間顯示格式
LC_NUMERIC: 數字顯示格式
LC_MONETARY: 貨幣顯示格式
LC_COLLATE: 字母順序與字符串比較
其中，與一般使用者最有關係的，是 LC_CTYPE 與 LC_MESSAGES 。
LC_CTYPE 直接關係到某些字符或內碼在目前的locale下是否可印? 要如何轉換? 對應到那一個字? .... 等等。
LC_MESSAGES 則關係到軟體的訊息輸出是什麼樣的語文。真正完整的locale支持，是當我們在shell prompt下，直接設好環境變數，則我們馬上就能切換到那個語言。

Solaris Locale的設置方法如下
查看當前locale狀態：
# locale
LANG=en_US
LC_CTYPE= "en_US"
LC_NUMERIC= "en_US"
LC_TIME= "en_US"
LC_COLLATE= "en_US"
LC_MONETARY= "en_US"
LC_MESSAGES= "en_US"
LC_ALL=en_US
查看系統中已安裝的語言包：
# locale -a
用戶自定義locale：
sh, ksh, bash:
# LANG=C; export LANG
# LC_ALL=C; export LC_ALL
csh:
# setenv LANG C
# setenv LC_ALL
或者編輯環境文件，只對當前用戶有效：
$HOME/.profile or $HOME/.cshrc
更改系統默認的locale，
修改文件：
vi /etc/default/init
example:
# Lines of this file should be of the form VAR=value, where VAR is one of
# TZ, LANG, or any of the LC_* environment variables.
LANG=C
LC_ALL=C
附錄：
You can change your system locale on UNIX and Linux systems.
You
can set environment variables to control the system locale. You can set
these variables to be system-wide, or on a per-session basis:
LC_ALL
Overrides all LC_* environment variables with the given value
LC_CTYPE
Character classification and case conversion
LC_COLLATE
Collation (sort) order
LC_TIME
Date and time formats
LC_NUMERIC
Non-monetary numeric formats
LC_MONETARY
Monetary formats
LC_MESSAGES
Formats of informative and diagnostic messages, and of interactive responses
LC_PAPER
Paper size
LC_NAME
Name formats
LC_ADDRESS
Address formats and location information
LC_TELEPHONE
Telephone number formats
LC_MEASUREMENT
Measurement units (Metric or Other)
LC_IDENTIFICATION
Metadata about the locale information
LANG
The default value, which is used when either LC_ALL is not set, or an applicable value for LC_* is not set
NLSPATH
Delimited list of paths to search for message catalogs
TZ
Time zone
LC_MESSAGES
and NLSPATH are the most important variables to the broker. These
variables define the language and location of response messages that the
broker uses. The broker profile file, mqsiprofile, sets NLSPATH. Either
you, or your system must set LC_MESSAGES. The value set in LC_MESSAGES
must be a value that the broker recognizes. LC_CTYPE is also important
to the broker because it defines the character conversion that the
broker performs when interacting with the local environment.
If you use common desktop environment (CDE), use this environment to
set the locale instead of setting LANG and LC_ALL directly. The NLSPATH
variable respects either method. Before setting the code page, check
that it is one of the Supported code pages.
For example, to set WebSphere® Message Broker to run in a UTF-8 environment set the following values in the profile:
LANG=en_US.utf-8
LC_ALL=en_US.utf-8
Where en_US sets the language, and utf-8 sets the code page.
