In the scope of S<C<use locale>>, Perl obeys the C<LC_CTYPE> locale
setting. This controls the application's notion of which characters are
alphabetic. This affects Perl's C<\w> regular expression metanotation,
-which stands for alphanumeric characters--that is, alphabetic and
-numeric characters. (Consult L<perlre> for more information about
+which stands for alphanumeric characters--that is, alphabetic,
+numeric, and including other special characters such as the underscore or
+hyphen. (Consult L<perlre> for more information about
regular expressions.) Thanks to C<LC_CTYPE>, depending on your locale
setting, characters like 'E<aelig>', 'E<eth>', 'E<szlig>', and
'E<oslash>' may be understood as C<\w> characters.
