First off, it's setlocale(LC_ALL, ""), not setlocale(LC_ALL, NULL). :)
Secondly, once you've done that, you cannot assume that the returned
locale string is any particular value. From the man page:
RETURN VALUE
A successful call to setlocale() returns an opaque string
that corresponds to the locale set.
"Opaque" means "don't look at this thing." :)
Use nl_langinfo(CODESET) to get the character encoding being used.
