What are the implications of working with Multibyte-Characters, such as German Umlauts, when manipulating strings in PHP?

Working with Multibyte-Characters, such as German Umlauts, in PHP can lead to issues with string manipulation functions that do not properly handle multibyte characters. To solve this, you can use the Multibyte String functions provided by PHP's Multibyte String extension (mbstring). This extension provides functions specifically designed to work with multibyte characters, ensuring proper handling of characters like German Umlauts. 

// Example of using mb_strlen to get the length of a string with multibyte characters
$string = "Müller";
$length = mb_strlen($string, 'UTF-8');
echo $length; // Output: 6
