Why is it important to specify the UTF-8 character set in both the index.php and detail.php files when dealing with special characters in PHP?

When dealing with special characters in PHP, it is important to specify the UTF-8 character set in both the index.php and detail.php files to ensure that the special characters are displayed correctly. This is necessary because UTF-8 is a widely used character encoding that supports a wide range of characters, including special characters. By specifying the UTF-8 character set, you are telling the browser how to interpret and display these characters properly. 

// index.php
<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>Index Page</title>
</head>
<body>
    <h1>Welcome to the Index Page</h1>
</body>
</html>

// detail.php
<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>Detail Page</title>
</head>
<body>
    <h1>Details about Special Characters</h1>
</body>
</html>
