Do not call setlocale()

notcurses_init() will call setlocale() to inspect the current locale. If that locale is “C” or “POSIX”, it will call setlocale(LC_ALL, “”) to set the locale according to the LANG environment variable. Ideally, this will result in UTF8 being enabled, even if the client app didn’t call setlocale() itself. Unless you’re certain that you’re invoking setlocale() prior to notcurses_init(), you should not set this bit. Even if you are invoking setlocale(), this behavior shouldn’t be an issue unless you’re doing something weird (setting a locale not based on LANG).
