localectl: Set a system locale variable.

localectl

$ localectl set-locale ${LANG}=${en_US-UTF-8}

try on your machine

The localectl set-locale command is used to set the system's default locale. A locale defines the language, character encoding, and other regional settings for a system.

In the given command, ${LANG} is a placeholder that represents the current value of the LANG environment variable. The LANG variable typically contains the current system locale.

The value en_US-UTF-8 provided after the equal sign (=) specifies the new locale that should be set. In this case, en represents English, US represents the United States, and UTF-8 refers to the Unicode character encoding. So, this command is setting the system's default locale to English (United States) with UTF-8 encoding.

For example, if the value of LANG is currently fr_FR.UTF-8, running the command localectl set-locale ${LANG}=${en_US-UTF-8} will change the system's default locale to English (United States) with UTF-8 encoding.
