What are some common pitfalls when trying to write special characters like € to a text file using PHP?

When writing special characters like € to a text file using PHP, a common pitfall is not specifying the correct character encoding. To ensure that special characters are properly written to the file, you should use the UTF-8 encoding. You can set the encoding using the `mb_internal_encoding()` function before writing the special characters to the file. 

<?php

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

// Open the file for writing
$file = fopen('special_chars.txt', 'w');

// Write the special character € to the file
fwrite($file, '€');

// Close the file
fclose($file);
