How can Umlaut characters be properly transmitted in PHP when using shell_exec() on Windows?

When using shell_exec() in PHP on Windows, Umlaut characters may not be properly transmitted due to encoding issues. To solve this problem, you can use the mb_convert_encoding() function to convert the string to the correct encoding before passing it to shell_exec(). This ensures that Umlaut characters are transmitted correctly. 

// Convert the string to the correct encoding
$command = mb_convert_encoding($command, 'Windows-1252', 'UTF-8');

// Execute the command using shell_exec()
$result = shell_exec($command);

// Output the result
echo $result;
