If you use $root->utf8_mode(0); (the default) and you pass decoded text to parse, you'll get decoded text from HTML::Element. When outputting the new HTML, encode it as normal. 

use strict;
use warnings;

use HTML::TreeBuilder;

# my $decoded_html = $http_response->decoded_content();
my $decoded_html = <<"__EOI__";
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Foo</title>
</head>
<body>\xC9ric</body>
</html>
__EOI__

my $t = HTML::TreeBuilder->new();
$t->parse($decoded_html);
$t->eof();

my $val = ( $t->content_list() )[1]->as_text();

binmode STDOUT, ":encoding(UTF-8)";
print(<<"__EOI__");
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Foo</title>
</head>
<body>Extracted $val</body>
</html>
__EOI__
