What are the potential SEO implications of using encoded URLs versus readable URLs with special characters?

Using encoded URLs with special characters can potentially impact SEO as search engines may have difficulty crawling and indexing these URLs. It is generally recommended to use readable URLs with relevant keywords for better SEO performance. 

// Convert special characters to readable format in URL
$url = "https://www.example.com/page?param=" . urlencode("special characters");
header("Location: " . $url);
exit;
