perl不在命令提示符下打印特殊字符

Question

Hi I wish to print result in command prompt as well as html file. I use encoding(cp1252) while printing in HTML however I can't see those special characters in the command prompt instead I am getting some junk values. For example "£" is printed as "ú". Thanks in advance

use strict;
use warnings;
use LWP::Simple;
use HTML::TreeBuilder::XPath;
use LWP::UserAgent;

my $competitor_declare='7shop';
my $xpath_declare='//strong';
my @urls = ("http://www.7dayshop.com/delivery-and-returns"); 


open HTML1, '>:encoding(cp1252)',"C:/Users/jeyakuma/Desktop/$competitor_declare.html";
open HTML, '>:encoding(cp1252)',"C:/Users/jeyakuma/Desktop/shipping project/database/$competitor_declare.html";  


foreach my $url (@urls)
        {
        print "\n\nworking on $url\n\n";
        my $ua = LWP::UserAgent->new( agent => "Mozilla/5.0" );
        my $req = HTTP::Request->new( GET => "$url" );
        my $res = $ua->request($req);

        if ( $res->is_success ) 
        {
           print "Please wait while we create file \n\n";
            my $xp = HTML::TreeBuilder::XPath->new_from_url($url);
           my $node = $xp->findnodes_as_string("$xpath_declare") or print "couldn't find the node\n"; #give xpath
            print HTML1 $node and print "Dump file is created please configure the same in xpathconfiguration.pl\n" and print HTML $node;
            print $node;
        }
        else{  
                print "file creation failed\n";

        }
}

Expected output in command prompt

cost is - £1.99

current result

cost is - ú1.99

7dayshop uses utf8 character set:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

There are two and ½ things you need to do on your windows machine to read utf8 on the console:

1. Modify your encoding of STDOUT using the following:

    binmode STDOUT, ':utf8:raw'; 

2. Change the encoding of your console using the following command before running your script:

    chcp 65001 

3. You might need to edit the font of your console to one like Lucida Console .

The following demonstrates my output on a windows machine:

use strict;
use warnings;
use autodie;

use LWP::Simple;
use HTML::TreeBuilder::XPath;
use LWP::UserAgent;

binmode STDOUT, ':utf8:raw';

my $competitor_declare = '7shop';
my $xpath_declare      = '//strong';
my @urls               = ("http://www.7dayshop.com/delivery-and-returns");

foreach my $url (@urls) {
    print "\n\nworking on $url\n\n";
    my $ua = LWP::UserAgent->new( agent => "Mozilla/5.0" );
    my $req = HTTP::Request->new( GET => "$url" );
    my $res = $ua->request($req);

    if ( $res->is_success ) {
        print "Please wait while we create file \n\n";
        my $xp = HTML::TreeBuilder::XPath->new_from_url($url);
        my $node = $xp->findnodes_as_string("$xpath_declare") or print "couldn't find the node\n";    #give xpath
        print $node;
    }
    else {
        print "file creation failed\n";
    }
}

Outputs:

working on http://www.7dayshop.com/delivery-and-returns

Please wait while we create file

Dump file is created please configure the same in xpathconfiguration.pl
