Re^5: sring encode problem (hexadecimal)

[JavaFan]

Works for me:

#!/usr/bin/perl

use 5.010;

use strict;
use warnings;

use HTML::Entities qw[encode_entities_numeric];
my $string = "\x{20AC}";
my $encoded = encode_entities_numeric $string;

say $encoded;

__END__

Hi JavaFan

Thank you for your code. you are right. now it is work indeed
however in your code
line 7 my $string = "\x{20AC}";
Is "\x{20AC}" equvalent to "€";??


why do you use my $string = "\x{20AC}"; instead of $string = "€";
would it be possible to use
my $string = "€"; ??
as i would pass value from form to it . these value would be any double byte character.




Many thanks

They are equivalent. I prefer to use \x{20AC} (and \x escapes in general) because that's encoding agnostic. If you write $string = "€";, I cannot see whether that's UTF-8, or perhaps ISO-8856-15.
