如何在HTML文件中输出中文

I have a form and insert some chinese words in database and it's ok. Table charset is UTF8. Problem appears when I select this data and send it via mail as HTML attachment. Then, Chinese doesn't display properly. How to fix charset before send data via mail? Should I use some headers and will it work?

My code looks like that:

//$attachedBodyContent is data from database that contains some chinese words
Mail::send(
            "emails.applicationTemplate",
            $data,
            function($message) use ($data, $template, $subject, $attachedBodyContent) {
                $message->to($data['email'], $data['name'])
                    ->from($template['from'],$template['from_name'])
                    ->subject($subject)
                    ->attachData($attachedBodyContent,'YourApplicationData.html');
              
            }
        );

</div>

When you generate .html attach file you should include in your <head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

In this case you can use this code for merge your content with <head>

<?php
    $header = '<!DOCTYPE html>
    <html>
    <head>
      <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    </head>
    <body>';
    $footer = '</body>
    </html>';
    $allContent = $header.$attachedBodyContent.$footer;
?>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

This should do it, for further information check the link.
