How can one troubleshoot and fix character encoding issues in PHP scripts?

Character encoding issues in PHP scripts can be troubleshooted and fixed by ensuring that the correct character encoding is specified in the script, using functions like mb_convert_encoding() to convert between different encodings, and setting the appropriate HTTP headers to indicate the encoding being used. 

// Specify the character encoding in the PHP script
header('Content-Type: text/html; charset=UTF-8');

// Convert encoding using mb_convert_encoding() function
$utf8_string = mb_convert_encoding($input_string, 'UTF-8', 'ISO-8859-1');

// Set the appropriate HTTP headers
header('Content-Type: text/html; charset=UTF-8');
