How can PHP developers avoid encoding issues when working with umlauts?

When working with umlauts in PHP, developers can avoid encoding issues by ensuring that their PHP files are saved with UTF-8 encoding and setting the appropriate charset in the HTML document. Additionally, using PHP functions like mb_convert_encoding() or utf8_encode() can help handle encoding properly. 

// Set the charset in the HTML document
header('Content-Type: text/html; charset=utf-8');

// Convert string to UTF-8 encoding
$umlautString = "Möglichkeiten";
$utf8String = utf8_encode($umlautString);

echo $utf8String;
