What steps can be taken to address encoding or character set issues when using htmlentities and nl2br in PHP?

When using htmlentities and nl2br in PHP, encoding or character set issues can arise if the input text contains special characters or is not in the expected character set. To address this, you can use the mb_convert_encoding function to convert the input text to the desired character set before applying htmlentities and nl2br functions. 

$inputText = "Hello, this is a test with special characters: áéíóú";
$charset = 'UTF-8';

// Convert input text to desired character set
$inputText = mb_convert_encoding($inputText, 'HTML-ENTITIES', $charset);

// Apply htmlentities and nl2br functions
$outputText = nl2br(htmlentities($inputText));

echo $outputText;
