What are the potential pitfalls of not properly encoding characters in PHP-generated links?

If characters in PHP-generated links are not properly encoded, it can lead to issues such as broken links, incorrect display of characters, and potential security vulnerabilities like cross-site scripting attacks. To solve this issue, it is important to use PHP's urlencode() function to properly encode characters in URLs. 

$url = "https://example.com/page.php?name=" . urlencode($name);
echo '<a href="' . $url . '">Link</a>';
