Locale

• LANGUAGE > LC_ALL > LANG
• LC_ALL overrides category-specific variables
• LANG provides a default for any category not set
• /etc/locale.conf is a systemdism from localectl
• If locale shows POSIX then foreign characters (e.g. Arabic) won’t display correctly unless LC_CTYPE=C.UTF-8 or LANG=en_US.UTF-8 are used

- *C (aka POSIX, micro optimization, disables UTF-8, performance)
- C.UTF-8 (glibcism?)
- en_US.UTF-8

## TERM
- *linux (tty, 8 colors)
- xterm-256color (default)
- tmux-256color vs screen-256color

## `POSIXLY_CORRECT` should be unset
