Add Support for Character Encoding

I would like to make a suggestion to support Page Character Encodings, being the default UTF-8.

On plugin attributes append:

'source_encoding' => 'UTF-8',
'target_encoding' => 'UTF-8',

Then when parsing the response

// strip the tags
...
// Convert the source encoding
if ( $source_encoding != $target_encoding ) {
$response = mb_convert_encoding($response, $target_encoding, $source_encoding);
}

// HTML encode the response
...

Too bad that we can’t make pull-requests like in GIT ??
What do you think about this feature ?
