How can Dropbox synchronization affect the display of characters with umlauts in PHP scripts accessing MySQL databases on different servers running different versions of PHP?

Dropbox synchronization can potentially corrupt files containing characters with umlauts, causing issues when accessing MySQL databases with PHP scripts on different servers running different PHP versions. To solve this issue, it is recommended to ensure that all files containing special characters are properly encoded and that the MySQL connection settings are consistent across servers. 

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

// Ensure that PHP scripts are using UTF-8 encoding
header('Content-Type: text/html; charset=utf-8');
mb_internal_encoding('UTF-8');
