%description
IO::HTML provides an easy way to open a file containing HTML while
automatically determining its encoding. It uses the HTML5 encoding sniffing
algorithm specified in section 8.2.2.2 of the draft standard.

The algorithm as implemented here is:

* 1.

If the file begins with a byte order mark indicating UTF-16LE, UTF-16BE, or
UTF-8, then that is the encoding.

* 2.

If the first '$bytes_to_check' bytes of the file contain a '<meta>' tag
that indicates the charset, and Encode recognizes the specified charset
name, then that is the encoding. (This portion of the algorithm is
implemented by 'find_charset_in'.)

The '<meta>' tag can be in one of two formats:

  <meta charset="...">
  <meta http-equiv="Content-Type" content="...charset=...">

The search is case-insensitive, and the order of attributes within the tag
is irrelevant. Any additional attributes of the tag are ignored. The first
matching tag with a recognized encoding ends the search.

* 3.

If the first '$bytes_to_check' bytes of the file are valid UTF-8 (with at
least 1 non-ASCII character), then the encoding is UTF-8.

* 4.

If all else fails, use the default character encoding. The HTML5 standard
suggests the default encoding should be locale dependent, but currently it
is always 'cp1252' unless you set '$IO::HTML::default_encoding' to a
different value. Note: 'sniff_encoding' does not apply this step; only
'html_file' does that.
