Actually, no.  Cygwin doesn't care for the default locale value itself.
It's the system default locale set and returned by setlocale(LC_ALL, "")
if none of the locale environment variables is set, per
http://www.opengroup.org/onlinepubs/7990989775/xbd/locale.html
The net result within Cygwin is the same, the charset is set to UTF-8.
