Do I need to use htmlspecialchars after using urlencode inside href or src attribute value?

Is it necessary to use htmlspecialchars after calling urlencode like this code:

<a href="file.php?var=<?php echo htmlspecialchars(urlencode($var)) ?>">Click here</a>

Or can I just write this:

<a href="file.php?var=<?php echo urlencode($var) ?>">Click here</a>
