Is it recommended to avoid converting special characters in URLs?

It is generally recommended to avoid converting special characters in URLs as it can lead to encoding issues and potential errors. Instead, it is better to use URL encoding to safely include special characters in URLs. This can be achieved using the PHP function urlencode() to encode special characters before appending them to the URL.

$special_character = "Hello, World!";
$encoded_special_character = urlencode($special_character);
$url = "https://example.com/?message=" . $encoded_special_character;
echo $url;
