Naturally, C<ord()> will do the reverse: turn a character to a code point.
-Note that C<\x..>, C<\x{..}> and C<chr(...)> for arguments less than
-0x100 (decimal 256) will generate an eight-bit character for backward
-compatibility with older Perls. For arguments of 0x100 or more,
-Unicode will always be produced. If you want UTF-8 always, use
-C<pack("U", ...)> instead of C<\x..>, C<\x{..}>, or C<chr()>.
+Note that C<\x..> (no C<{}> and only two hexadecimal digits), C<\x{...}>
+and C<chr(...)> for arguments less than 0x100 (decimal 256) will

You can also use the C<charnames> pragma to invoke characters
by name in doublequoted strings:
my $georgian_an = pack("U", 0x10a0);
+Note that both C<\x{...}> and C<\N{...}> are compile-time string
+constants: you cannot use variables in them. if you want similar
+run-time functionality, use C<chr()> and C<charnames::vianame()>.

=head2 Handling Unicode
Handling Unicode is for the most part transparent: just use the
=back
+=head1 UNICODE IN OLDER PERLS
+
+If you cannot upgrade your Perl to 5.8.0 or later, you can still
+do some Unicode processing by using the modules C<Unicode::String>,
+C<Unicode::Map8>, and C<Unicode::Map>, available from CPAN.
+If you have the GNU recode installed, you can also use the
+Perl frontend C<Convert::Recode> for character conversions.
