What potential issues can arise when handling character encoding in PHP?

One potential issue that can arise when handling character encoding in PHP is dealing with different character sets, which can lead to garbled or incorrect output. To solve this, it is important to ensure that all input and output is consistently encoded in the same character set, such as UTF-8. 

// Set the default character encoding to UTF-8
header('Content-Type: text/html; charset=utf-8');
mb_internal_encoding('UTF-8');
mb_http_output('UTF-8');
