What potential issues can arise when encoding Umlaut characters in PHP scripts?

When encoding Umlaut characters in PHP scripts, potential issues can arise if the script is not properly configured to handle UTF-8 encoding. This can result in the Umlaut characters being displayed incorrectly or not at all. To solve this issue, make sure to set the appropriate encoding for your PHP script to UTF-8 using the header() function. 

header('Content-Type: text/html; charset=utf-8');
