What are some potential pitfalls when using setlocale() in PHP for character encoding?

When using setlocale() in PHP for character encoding, a potential pitfall is that it may not work as expected on all systems or may not support all character encodings. To ensure compatibility and avoid issues, it's recommended to use the mb_internal_encoding() function to set the character encoding explicitly. 

// Set the character encoding explicitly using mb_internal_encoding()
mb_internal_encoding('UTF-8');

// Use setlocale() for other locale settings if needed
setlocale(LC_ALL, 'en_US.UTF-8');
