What are the potential issues with using Latin1 as a charset in PHP applications and how can they be addressed?

Using Latin1 as a charset in PHP applications can lead to encoding issues when handling non-Latin characters, as Latin1 does not support a wide range of characters. To address this, it is recommended to use UTF-8 as the charset in PHP applications to ensure proper handling of different character sets.

// Set UTF-8 as the charset in PHP
header('Content-Type: text/html; charset=utf-8');
