| Environment variables / Operating system environment variables | |
Defines the current application locale on UNIX™ platforms.
The LC_ALL (or LANG) environment variable defines language, territory and codeset for programs running on UNIX platforms.
The codeset defined in LC_ALL is used by the runtime system to handle character strings.
It is important to set this variable properly according to the character set used by your application.
If LC_ALL is not defined, LANG is used instead.
Read the UNIX man page of the setlocale() C function for more details about this variable.
