locale_get_script() Gets the script for the input locale
locale_get_region() Gets the region for the input locale
locale_get_all_variants() Gets the variants for the input locale

The behaviour when a falsy value is passed as the $locale is undocumented, but it appears that it returns the primary language of the default system language. In my case:
  Locale::getPrimaryLanguage(null);
Returns 'en'. So make sure to test $locale before passing it to the method.
