=head1 NAME

Encode::Detect - An Encode::Encoding subclass that detects the encoding of data

=head1 SYNOPSIS

  use Encode;
  require Encode::Detect;
  my $utf8 = decode("Detect", $data);

=head1 DESCRIPTION

This Perl module is an Encode::Encoding subclass that uses
Encode::Detect::Detector to determine the charset of the input data
and then decodes it using the encoder of the detected charset.

It is similar to Encode::Guess, but does not require the configuration
of a set of expected encodings.  Like Encode::Guess, it only supports
decoding--it cannot encode.
