saveHTMLFile() always saves the file in UTF-8. Even if the DOMDocument->encoding explicitly prescribe different from UTF-8 encoding. All "non-Latin" characters will be converted to HTML-entities. Tested in PHP 5.2.9-2 and PHP 5.2.17. Example:

<?php
$document
=new domDocument('1.0', 'WINDOWS-1251');
$document->loadHTML('<html><head><title>Russian language</title></head><body>Русский язык</body></html>');
$document->formatOutput=true;
$document->encoding='WINDOWS-1251';
echo
"Записано байт. Recorded bytes: ".$document->saveHTMLFile('html.html');
?>

Method recorded file in UTF-8 encoding. The contents of the file html.html:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Russian language</title>
</head>
<body>Ðóññêèé ÿçûê</body>
</html>

I foolishly assumed that this function was equivalent to
<?php
file_put_contents
($filename, $document->saveHTML());
?>
but there are differences in the generated HTML:
<?php
$doc
= new DOMDocument();
$doc->loadHTML(
   
'<html><head><title>Test</title></head><body></body></html>'
);
$doc->encoding = 'iso-8859-1';

echo
$doc->saveHTML();
#<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
#<html>
#<head><title>Test</title></head>
#<body></body>
#</html>

$doc->saveHTMLFile('output.html');
#<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
#<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Test</title></head><body></body></html>

?>
Note that saveHTMLFile() adds a UTF-8 meta tag despite the ISO-8859-1 document encoding.

Not mentioned in the documentation is the fact that using DOMDocument::saveHTMLFile() will automatically overwrite the contents if an existing file is used - with no notice, warning or error thrown.

Make sure you check the filename before using this function so that you don't accidentally overwrite important files.

Example:
<?php

$file
= fopen('test.html', 'w');
fwrite($file, 'this is some text');
fclose($file);

$doc = new DOMDocument();
$doc->formatOutput = true;
$doc->loadHTML('<html><head><title>Test</title></head><body></body></html>');
$doc->saveHTMLFile('test.html');

// test.html
/*
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Test</title>
</head>
<body></body>
</html>
*/

?>

If you're dynamically generating a series of pages using DOMDocument objects, make sure you are also dynamically generating the file or directory names using something that can't easily be confused for an existing file/folder, or check if the desired path already exists before saving so that you don't accidentally delete previous files.
