Hello,

The best and easiest solution is using a Premium license, that includes HTML Extended features. For this specific case, you can do a minor change in the library:

Edit HTML2WordML.php in the classes folder, and in the method generateRPr (around line 1859), add these lines after the line-through check:

if (isset($properties['text_decoration']) && $properties['text_decoration'] == 'double-underline') {
    $stringRPr .='<w:u w:val="double" />';
}

Instead of this code:

if (isset($properties['text_decoration']) && $properties['text_decoration'] == 'line-through') {
    $stringRPr .='<w:strike />';
}
if (!$this->strictWordStyles) {

this is the code updated:

if (isset($properties['text_decoration']) && $properties['text_decoration'] == 'line-through') {
    $stringRPr .='<w:strike />';
}
if (isset($properties['text_decoration']) && $properties['text_decoration'] == 'double-underline') {
    $stringRPr .='<w:u w:val="double" />';
}
if (!$this->strictWordStyles) {

After this change, you can use the custom double-underline value to apply a double underline style in texts:

$html = '
<style>
    .underline {
        text-decoration: underline;
    }
    .dunderline {
        text-decoration: double-underline;
    }
</style>
';
$html .= '<p><span class="underline">Underline</span> and <span class="dunderline">double underline</span>.</p>';
$docx->embedHTML($html);

Regards.
