You can get a list of all locales installed on your system (usually in /usr/lib/locale/) with the command locale -a. Set the environment variable LANG to the name of your preferred locale. When a C program executes the setlocale(LC_CTYPE, "") function, the library will test the environment variables LC_ALL, LC_CTYPE, and LANG in that order, and the first one of these that has a value will determine which locale data is loaded for the LC_CTYPE category (which controls the multibyte conversion functions). The locale data is split up into separate categories. For example, LC_CTYPE defines the character encoding and LC_COLLATE defines the string sorting order. The LANG environment variable is used to set the default locale for all categories, but the LC_* variables can be used to override individual categories.
