What are common issues with displaying Umlaut characters in PHP scripts and databases?

Common issues with displaying Umlaut characters in PHP scripts and databases often arise due to character encoding mismatches. To solve this, make sure that your PHP files are saved with UTF-8 encoding, and that your database tables and connection are also set to use UTF-8 encoding. Additionally, use functions like utf8_encode() and utf8_decode() when working with strings that contain Umlaut characters. 

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

// Set UTF-8 encoding for database connection
$mysqli = new mysqli("localhost", "username", "password", "database");
$mysqli->set_charset("utf8");

// Use utf8_encode() and utf8_decode() when working with Umlaut characters
$text_with_umlaute = "Möglichkeit";
$text_encoded = utf8_encode($text_with_umlaute);
echo utf8_decode($text_encoded);
