What resources or documentation can be helpful in troubleshooting and resolving UTF-8 encoding issues in PHP?

UTF-8 encoding issues in PHP can arise when handling multibyte characters or when displaying text in different languages. To troubleshoot and resolve these issues, it's important to ensure that your PHP files are saved with UTF-8 encoding, set the appropriate charset in the HTML meta tag, use mbstring functions for multibyte string operations, and sanitize user input to prevent encoding errors. 

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

// Convert string to UTF-8
$string = "Some text with special characters like café";
$utf8_string = mb_convert_encoding($string, 'UTF-8', 'auto');

// Output UTF-8 encoded string
echo $utf8_string;
