How can PHP developers ensure consistent encoding and decoding of Umlaut characters in form submissions and data processing?

To ensure consistent encoding and decoding of Umlaut characters in form submissions and data processing, PHP developers can use the mb_convert_encoding function to convert the input data to the desired encoding (e.g., UTF-8) before processing it. This ensures that Umlaut characters are handled correctly throughout the application. 

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

// Process the input data
// (Add your data processing logic here)
