What are some common challenges faced when trying to manipulate strings with special characters like umlauts in PHP?

When manipulating strings with special characters like umlauts in PHP, a common challenge is dealing with character encoding. It is important to ensure that the correct character encoding is used throughout the application to properly handle special characters. One solution is to use functions like mb_convert_encoding() to convert strings to the desired encoding before manipulating them. 

// Example code snippet to handle strings with special characters like umlauts

// Input string with umlauts
$inputString = "Möglichkeiten für Öffnungszeiten";

// Convert input string to UTF-8 encoding
$inputString = mb_convert_encoding($inputString, 'UTF-8');

// Manipulate the string as needed
$outputString = strtoupper($inputString);

// Output the manipulated string
echo $outputString;
