Here's a way to reverse a Unicode string using the regular expression character class \X to match Unicode extended grapheme clusters:

my $edocinU = join '', reverse $Unicode =~ m/\X/g;

Here's a demonstration using Vietnamese (tiếng Việt) words:

#!perl

use strict;
use warnings;
use utf8;

binmode STDOUT, ':encoding(UTF-8)';

my $Moonshine = "Rượu đế";
my $enihsnooM = join '', reverse $Moonshine =~ m/\X/g;

print "$Moonshine\n";
print "$enihsnooM\n";

__END__
Rượu đế
ếđ uợưR

LATIN CAPITAL LETTER R
LATIN SMALL LETTER U
COMBINING HORN
LATIN SMALL LETTER O
COMBINING HORN
COMBINING DOT BELOW
LATIN SMALL LETTER U
SPACE
LATIN SMALL LETTER D WITH STROKE
LATIN SMALL LETTER E
COMBINING CIRCUMFLEX ACCENT
COMBINING ACUTE ACCENT

[I was forced to use <pre> tags instead of <code> tags here to display the actual Vietnamese characters rather than their HTML character entities.]

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
