That should do. It seems there's no uri_unescape_utf8 in URI::Escape.

In the simplest case, the original character sequence contains only characters that are defined in US-ASCII, and the two levels of mapping are simple and easily invertible: each 'original character' is represented as the octet for the US-ASCII code for it, which is, in turn, represented as either the US-ASCII character, or else the "%" escape sequence for that octet.

For original character sequences that contain non-ASCII characters, however, the situation is more difficult. Internet protocols that transmit octet sequences intended to represent character sequences are expected to provide some way of identifying the charset used, if there might be more than one rfc RFC 2277. However, there is currently no provision within the generic URI syntax to accomplish this identification. An individual URI scheme may require a single charset, define a default charset, or provide a way to indicate the charset used.

That code works properly on my computer, it is probably just a visualization effect; my console is UTF-8 and shows the proper accented letters, ie ì

i'm not so sure. i modified my code to:

#!/usr/bin/perl

use strict;
use warnings;

use URI::Escape;

my $terms = "%22Celades%22+%22Aspectos+cl%C3%ADnicos+*+*+menopausia%22
+";

print "Expecting: \"Celades\"+\"Aspectos+clínicos+*+*+menopausia\"\n";
print "Returning: ",uri_unescape($terms),"\n";

exit;

and it returned:

Expecting: "Celades"+"Aspectos+clínicos+*+*+menopausia"
Returning: "Celades"+"Aspectos+clínicos+*+*+menopausia"

if it were a visual thing wouldnt they both be wrong?

perhaps it is to do with the version of URI::Escape? mine is 3.28, yours?
