Perl: printing Unicode strings to the Windows console

问题

I am encountering a strange problem in printing Unicode strings to the Windows console*.

Consider this text:

אני רוצה לישון

Intermediary

היא רוצה לישון
אתם, הם
Bye
Hello, world!
test

Assume it's in a file called "file.txt".

When I go*: "type file.txt", it prints out fine. But when it's printed from a Perl program, like this:

 use strict;
 use warnings;
 use Encode;
 use 5.014;
 use utf8;
 use autodie;
 use warnings    qw< FATAL  utf8     >;
 use open        qw< :std  :utf8     >;
 use feature     qw< unicode_strings >;
 use warnings 'all';

 binmode STDOUT, ':utf8';   # output should be in UTF-8
 my $word;
 my @array = ( 'אני רוצה לישון', 'Intermediary',
    'היא רוצה לישון', 'אתם, הם', 'Bye','Hello, world!', 'test');
 foreach $word(@array) {
    say $word;
 }

The Unicode lines (Hebrew in this case) show up again each time, partially broken, like this:

E:\My Documents\Technical\Perl>perl "hello unicode.pl"
אני רוצה לישון
לישון
�ן

Intermediary
היא רוצה לישון
לישון
�ן

אתם, הם
�ם

Bye
Hello, world!
test

(I save everything in UTF-8).

This is mighty strange. Any suggestions?

(It's not a "Console2" problem* - the same problem shows up on a "regular" windows console, only there you don't see the Hebrew glyphs).

* Using "Console" (also called "Console2") - it's a nice little utility which enables working with Unicode with the Windows console - see, for example, here: http://www.hanselman.com/blog/Console2ABetterWindowsCommandPrompt.aspx

** Note: at the console, you have to say, of course:

chcp 65001

Did you try the solution from perlmonk ?

It use :unix as well to avoid the console buffer.

This is the code from that link:

use Win32::API;

binmode(STDOUT, ":unix:utf8");

#Must set the console code page to UTF8
$SetConsoleOutputCP= new Win32::API( 'kernel32.dll', 'SetConsoleOutputCP', 'N','N' );
$SetConsoleOutputCP->Call(65001);

$line1="\x{2554}".("\x{2550}"x15)."\x{2557}\n";
$line2="\x{2551}".(" "x15)."\x{2551}\n";
$line3="\x{255A}".("\x{2550}"x15)."\x{255D}";
$unicode_string=$line1.$line2.$line3;

print "THIS IS THE CORRECT EXAMPLE OUTPUT IN PURE PERL: \n";
print $unicode_string;

Guys: continuing on studying that Perlmonks post, turns out that this is even neater and nicer: replace:
use Win32::API;
and:

$SetConsoleOutputCP= new Win32::API( 'kernel32.dll', 'SetConsoleOutputCP', 'N','N' );
$SetConsoleOutputCP->Call(65001);

with:

use Win32::Console;

and:

 Win32::Console::OutputCP(65001);

Leaving all else intact.
This is even more in the spirit of Perl conciseness and magic.

回答3:

You can also utilize Win32::Unicode::Console or Win32::Unicode::Native to achieve unicode prints on windows console.

回答4:

Also, this behaviour is not present while using ConEmu, which also enables proper Unicode support in Windows' command console.
