How can the use of htmlentities and utf8_encode functions in PHP help address issues related to special characters in generated content like RSS feeds?

Special characters in generated content like RSS feeds can cause display issues if not properly encoded. Using htmlentities function in PHP helps convert special characters to HTML entities, ensuring they are displayed correctly in the feed. Additionally, utf8_encode function can be used to convert the content to UTF-8 encoding, which is commonly used for web content and helps prevent character encoding issues. 

// Example code snippet to encode special characters in generated content for RSS feeds
$content = "Special characters like é, ü, and © can cause display issues in RSS feeds";
$encoded_content = htmlentities(utf8_encode($content));

echo $encoded_content;
