While making a QR code for my encrypted link I noticed that the " + " sign wasn't included in the QR code.

Sample link: `http://localhost/cp//form?ASLV2N0+YmkHz6ELPjgEoqbA7qYQ69eoTReV9jSwEviaqJi8j54kQmpbaVK58LlFZmjhKG+X3uyPpZ6fC0/H2A==`

Is there anyway to remove the + symbol in my encryption?
This is how I encrypt my link:

```
$cryptKey = 'qJB0rGtIn5UB1xG03efyCp';
$qEncoded = base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, md5($cryptKey),
                          $q,
                          MCRYPT_MODE_CBC,
                          md5(md5($cryptKey))));

```
