DomDocument and special characters

This is my code:

$oDom = new DOMDocument();
$oDom->loadHTML("èàéìòù");
echo $oDom->saveHTML();

This is the output:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html><body><p>&Atilde;&uml;&Atilde;&nbsp;&Atilde;&copy;&Atilde;&not;&Atilde;&sup2;&Atilde;&sup1;</p></body></html>

I want this output:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html><body><p>èàéìòù</p></body></html>

I've tried with ... 

$oDom = new DomDocument('4.0', 'UTF-8');

or with 1.0 and other stuffs but nothing.

Another thing ... There is a way to obtain the same untouched HTML? For example with this html in input <p>hello!</p> obtain the same output <p>hello!</p> using DOMDocument only for parsing the DOM and to do some substitutions inside the tags.

$dom = new DomDocument();
$str = htmlentities($str);
$dom->loadHTML(utf8_decode($str));
$dom->encoding = 'utf-8';
.
.
.
$str = $dom->saveHTML();
$str = html_entity_decode($str);

The above code worked for me.

This way:

/**
 * @param string $text
 * @return DOMDocument
 */
private function buildDocument($text)
{
    $dom = new DOMDocument();

    libxml_use_internal_errors(true);
    $dom->loadHTML('<meta http-equiv="Content-Type" content="text/html; charset=utf-8">' . $text);
    libxml_use_internal_errors(false);

    return $dom;
}

I don't know why the marked answer didn't work for my problem. But this one did.

ref: https://www.php.net/manual/en/class.domdocument.php

<?php

            // checks if the content we're receiving isn't empty, to avoid the warning
            if ( empty( $content ) ) {
                return false;
            }

            // converts all special characters to utf-8
            $content = mb_convert_encoding($content, 'HTML-ENTITIES', 'UTF-8');

            // creating new document
            $doc = new DOMDocument('1.0', 'utf-8');

            //turning off some errors
            libxml_use_internal_errors(true);

            // it loads the content without adding enclosing html/body tags and also the doctype declaration
            $doc->LoadHTML($content, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);

            // do whatever you want to do with this code now

?>

None of the above worked for me but this one did the job:

$fileContent = file_get_contents('my_file.html');
$dom = new DOMDocument();
@$dom->loadHTML(mb_convert_encoding($fileContent, 'HTML-ENTITIES', 'UTF-8'), LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);
$dom->encoding = 'utf-8';
$html = $dom->saveHTML();
$html = html_entity_decode($html, ENT_COMPAT, 'UTF-8');
echo $html;
