Decode UTF-8 URL in Perl

Consider:

use URI::Escape;
print uri_unescape("%C3%B3");

Output : ó

Decode with this http://meyerweb.com/eric/tools/dencoder/

Output : ó

This is the expected one.

What Perl library should I use to get the correct output?

Solution

  • If you know that the byte sequence is UTF-8, then use Encode::decode:

    use Encode;
use URI::Escape;

my $in = "%C3%B3";
my $text = Encode::decode('utf8', uri_unescape($in));

print length($text);    # Should print 1
