How can developers troubleshoot and resolve issues related to unexpected character encoding discrepancies, such as the appearance of additional characters like à in MySQL data stored from PHP forms?

Issue: The unexpected character encoding discrepancies, such as the appearance of additional characters like à in MySQL data stored from PHP forms, can be resolved by ensuring that the character encoding settings are consistent throughout the application. This can be achieved by setting the appropriate character encoding for the database connection, PHP script, and HTML output. PHP Code Snippet:

// Set character encoding for database connection
mysqli_set_charset($connection, 'utf8');

// Set character encoding for PHP script
header('Content-Type: text/html; charset=utf-8');

// Set character encoding for HTML output
echo '<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">';
