Those set LANG. There's also the hardcoded fallback to "C.UTF-8" in
setlocale() in case none of LC_ALL, LC_FOO, and LANG is set. This is
Cygwin's system default locale as per POSIX Base defs section 7.2
("All implementations shall define a locale as the default locale, to
be invoked when no environment variables are set, or set to the empty
string. This default locale can be the POSIX locale or any other
implementation-defined locale.")
