Codex:

Attempts an early load of translations.

Used for errors encountered during the initial loading process, before the locale has been properly detected and loaded. Designed for unusual load sequences (like setup-config.php) or for when the script will then terminate with an error, otherwise there is a risk that a file can be double-included.
