my $res = $ua->get("http://www.example.com/");

Nothing.

METHODS

This module adds the following methods to HTTP::Response objects.
"$res->charset"
Tells the charset exactly as appears in the "Content-Type:" header. Note that the presence of the charset does not guarantee if the response content is decodable via Encode.

To normalize this, you should try 

  $res->encoder->mime_name; # with Encode 2.21 or above

or 

  use I18N::Charset;
  # ...
  mime_charset_name($res->encoding);
"$res->encoder"
Returns the corresponding encoder object or undef if it can't.
"$res->encoding"
Tells the content encoding in the canonical name in Encode. Returns undef if it can't.

For most cases, you are more likely to successfully find encoding after GET than HEAD. HTTP::Response is smart enough to parse 

  <meta http-equiv="Content-Type" content="text/html; charset=whatever"/>

But you need the content to let HTTP::Response parse it. If you don't want to retrieve the whole content but interested in its encoding, try something like below; 

  my $req =  HTTP::Request->new(GET => $uri);
  $req->headers->header(Range => "bytes=0-4095"); # just 1st 4k
  my $res = $ua->request($req);
  warn $res->encoding;
"$res->decoded_content"
Discontinued since HTTP::Message already has this method.

See HTTP::Message for details.
