How can one address and resolve character encoding issues, such as Umlaut problems, in PHP?

Character encoding issues, such as Umlaut problems, can be addressed and resolved in PHP by ensuring that the correct character encoding is set in the PHP file and the HTML document. This can be done by using functions like mb_internal_encoding() and mb_http_output() to set the encoding to UTF-8. Additionally, using htmlentities() or htmlspecialchars() functions can help encode special characters properly. 

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

// Example of encoding special characters using htmlentities
$text = "Möglichkeit";
echo htmlentities($text, ENT_QUOTES, 'UTF-8');
