=head1 DESCRIPTION
The Perl parser will expand $variable and @variable references in
regular expressions unless the delimiter is a single quote. Remember,
-too, that the right-hand side of an C<s///> substitution is considered
+too, that the right-hand side of a C<s///> substitution is considered
a double-quoted string (see L<perlop> for more details). Remember
also that any regex special characters will be acted on unless you
precede the substitution with \Q. Here's an example:
=head2 How can I match strings with multibyte characters?
-This is hard, and there's no good way. Perl does not directly support
-wide characters. It pretends that a byte and a character are
-synonymous. The following set of approaches was offered by Jeffrey
-Friedl, whose article in issue #5 of The Perl Journal talks about this
-very matter.
+Starting from Perl 5.6 Perl has had some level of multibyte character
+support. Perl 5.8 or later is recommended. Supported multibyte
+character repetoires include Unicode, and legacy encodings
+through the Encode module. See L<perluniintro>, L<perlunicode>,
+and L<Encode>.
+
+If you are stuck with older Perls, you can do Unicode with the
+C<Unicode::String> module, and character conversions using the
+C<Unicode::Map8> and C<Unicode::Map> modules. If you are using
+Japanese encodings, you might try using the jperl 5.005_03.

Let's suppose you have some weird Martian encoding where pairs of
ASCII uppercase letters encode single Martian letters (i.e. the two
