How can developers ensure that their text editors do not introduce unwanted characters that affect PHP scripts?

Developers can ensure that their text editors do not introduce unwanted characters that affect PHP scripts by configuring their text editor to save files with UTF-8 encoding without a Byte Order Mark (BOM). This will prevent any invisible characters from being added to the PHP scripts and causing issues. 

<?php
// Ensure that the PHP script is saved with UTF-8 encoding without a BOM
// Add this line at the beginning of the PHP script to specify the encoding
header('Content-Type: text/html; charset=utf-8');
