What are some common issues with handling special characters like umlauts in PHP when interacting with MySQL databases?

When handling special characters like umlauts in PHP when interacting with MySQL databases, a common issue is character encoding mismatch between PHP and MySQL. To solve this, make sure both PHP and MySQL are using the same character encoding, such as UTF-8. You can set the character set in MySQL connection and also specify the character set in PHP when connecting to the database. 

// Set character set in MySQL connection
$mysqli = new mysqli("localhost", "username", "password", "database");
$mysqli->set_charset("utf8");

// Specify character set in PHP
mysqli_set_charset($mysqli, "utf8");
