How can PHP developers address and resolve issues related to charset encoding when working with Umlauts in their code?

When working with Umlauts in PHP code, developers may encounter charset encoding issues, especially when handling input/output operations with non-ASCII characters. To address this problem, developers can ensure that their PHP files are saved with the correct character encoding (such as UTF-8) and use PHP functions like mb_convert_encoding() to handle conversions between different charsets. 

// Set the default charset to UTF-8
header('Content-Type: text/html; charset=utf-8');

// Convert input string to UTF-8 encoding
$input = 'Möglichkeiten';
$input_utf8 = mb_convert_encoding($input, 'UTF-8', 'auto');

// Output the UTF-8 encoded string
echo $input_utf8;
