How can PHP developers ensure proper encoding (e.g., UTF-8) to handle umlauts and special characters effectively in their applications?

To ensure proper encoding like UTF-8 for handling umlauts and special characters in PHP applications, developers should set the character encoding explicitly in their PHP files using header() function or meta tags in HTML. Additionally, they can use functions like mb_internal_encoding() and mb_convert_encoding() to handle string encoding and conversion effectively. 

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

// Set internal encoding to UTF-8
mb_internal_encoding('UTF-8');

// Convert string to UTF-8 encoding
$utf8_string = mb_convert_encoding($original_string, 'UTF-8', 'auto');
