locale.conf - Configuration file for locale settings
The /etc/locale.conf file configures system-wide locale settings. It is
read at early-boot by systemd(1).
The basic file format of locale.conf is a newline-separated list of
environment-like shell-compatible variable assignments. It is possible
to source the configuration from shell scripts, however, beyond mere
variable assignments, no shell features are supported, allowing
applications to read the file without implementing a shell compatible

locale.LANGUAGE=, locale.LC_CTYPE=, locale.LC_NUMERIC=,
locale.LC_TIME=, locale.LC_COLLATE=, locale.LC_MONETARY=,
locale.LC_MESSAGES=, locale.LC_PAPER=, locale.LC_NAME=,
locale.LC_ADDRESS=, locale.LC_TELEPHONE=, locale.LC_MEASUREMENT=,
locale.LC_IDENTIFICATION= may be used to override the locale settings
The locale settings configured in /etc/locale.conf are system-wide and
are inherited by every service or user, unless overridden or unset by
individual programs or individual users.
Depending on the operating system, other configuration files might be
checked for locale configuration as well, however only as fallback.
The following locale settings may be set using /etc/locale.conf: LANG=,
LANGUAGE=, LC_CTYPE=, LC_NUMERIC=, LC_TIME=, LC_COLLATE=, LC_MONETARY=,
LC_MESSAGES=, LC_PAPER=, LC_NAME=, LC_ADDRESS=, LC_TELEPHONE=,
LC_MEASUREMENT=, LC_IDENTIFICATION=. Note that LC_ALL may not be
configured in this file. For details about the meaning and semantics of
these settings, refer to locale(7).
