Dear Monks,
Could someone please explain the following output?
#!/usr/bin/perl -w
use strict;
use Encode;
use Data::Dumper;
my $string1 = "blëh";
my $string2 = "blëhh";
my $string3 = "blëh.txt";
$string1 = Encode::decode(utf8 => $string1);
$string2 = Encode::decode(utf8 => $string2);
$string3 = Encode::decode(utf8 => $string3);
$Data::Dumper::Useqq = 1;
print Dumper $string1, $string2, $string3;
print "matches1\n" if ($string1 =~ /^[\w\s.]+$/);
print "matches2\n" if ($string2 =~ /^[\p{Word}]+$/);
print "matches3\n" if ($string3 =~ /^[\p{L}\p{M}\p{N}.]+$/);
##### output #####
$VAR1 = "bl";
$VAR2 = "bl\x{fffd}hh";
$VAR3 = "bl\x{fffd}h.txt";
matches1
(Perl version is 5.8.4)
As far as I can see, string1 should not match but does (look at the weird Dumper output), while string2 and string3 don't match, but should.

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.
