LANG gives a weak default to each LC_* in case it is not explicitly
defined. LC_ALL, if set, overrides all other LC_* variables.
LANG < LC_CTYPE, LC_COLLATE, LC_MONETARY, LC_NUMERIC, ... < LC_ALL
This is why documentation such as [1] suggests to set LC_ALL in build
scripts to get the deterministic result.
LANG=C is not strong enough to override LC_* that may be set by end
users.
