The only sane way to deal with unicode IO is to keep everything correctly flagged as being either in the "internal multibyte encoding" or binary/8-bit, use IO layers for input/output, use Encode::decode() to interpret binary strings directly if you have to, and never, ever use Encode::encode():

I have to download unspecified web pages and process them as unicode with HTML::Tree though; in this case, how can I avoid using Encode::encode() - I need to pass the data onto the parser:
  $fsuccess = ($response = $ua->get($url))->is_success;
  die "Could not fetch URI '" . $url . "'\n" unless $fsuccess;
  $decoded = $response->decoded_content;
  die "Could not decode content" unless $decoded;
  $utf8 = Encode::encode_utf8($decoded);

  $tree = HTML::TreeBuilder->new();
  $tree->utf8_mode(1);
  die "Parse error" unless $tree->parse($utf8);
  $tree->eof();
