What are the best practices for ensuring consistent character encoding across PHP files, HTML headers, form tags, and email headers?

In order to ensure consistent character encoding across PHP files, HTML headers, form tags, and email headers, it is best practice to set the character encoding to UTF-8 in all these areas. This will help prevent encoding issues and ensure that text is displayed correctly across different platforms and devices. 

// Set the character encoding in PHP files
header('Content-Type: text/html; charset=utf-8');

// Set the character encoding in HTML headers
<meta charset="utf-8">

// Set the character encoding in form tags
<form accept-charset="UTF-8">

// Set the character encoding in email headers
$headers = 'Content-Type: text/html; charset=UTF-8';
