Are there any best practices for setting the default encoding in PHP scripts?

Setting the default encoding in PHP scripts is important to ensure that your application can handle different character sets properly. One common best practice is to set the default encoding to UTF-8, which supports a wide range of characters and is widely used on the web. This can be done using the `ini_set()` function in PHP.

// Set default encoding to UTF-8
ini_set('default_charset', 'UTF-8');
