How can differences in PHP and MySQL versions between local and web hosting environments affect the storage of UTF-8 characters, particularly umlauts?

Differences in PHP and MySQL versions between local and web hosting environments can affect the storage of UTF-8 characters, particularly umlauts, due to variations in how character encoding is handled. To ensure consistent storage and retrieval of UTF-8 characters, it is important to set the character set and collation in both PHP and MySQL to UTF-8. 

// Set UTF-8 character set and collation in PHP
mysqli_set_charset($connection, "utf8");

// Set UTF-8 character set and collation in MySQL
mysqli_query($connection, "SET NAMES 'utf8'");
mysqli_query($connection, "SET CHARACTER SET utf8");
mysqli_query($connection, "SET COLLATION_CONNECTION = 'utf8_general_ci'");
