What steps should be taken to ensure that all components (database, tables, columns, PHP script, HTML document) are properly UTF-8 encoded?

To ensure that all components are properly UTF-8 encoded, you should set the character encoding to UTF-8 in your database, tables, and columns. Additionally, make sure that your PHP scripts and HTML documents are also UTF-8 encoded by setting the header and meta tags accordingly. 

// Set UTF-8 encoding for database connection
$mysqli->set_charset("utf8");

// Set UTF-8 encoding for PHP scripts
header('Content-Type: text/html; charset=utf-8');

// Set UTF-8 encoding for HTML documents
<meta charset="UTF-8">
