Locale command

The locale command is used to set the locale in which the program runs.

Locale sets the naming convention for the locale to Language_area.charset, such as En_us.utf8, which represents the English language, the region is the United States, and the character set is UTF-8.

Set the default encoding

Edit ~/.BASHRC, set the default encoding to UTF-8:

Export lc_all=en_us.utf8export LANG= $LC _all

The environment variable LANG is the default value for lc_* and is used if no lc_* is set.

Lc_all is a macro that overrides all lc_* values except LANG if the value is set.
