Description:
------------
I am using the base64_encode() function to send attachements by email.
When I receive the mail on Outlook, the attachement is visible but corrupeted.
I have tested the whole process and my conclusion is that the base64_encode() function does not work correctly.
I have made a workarround with an extrenal program that performs the base64 encoding and it work correctly.


Reproduce code:
---------------
    function EncodeString ($str, $encoding = "base64") {
        $encoded = "";
        switch(strtolower($encoding)) {
          case "base64":
              $encoded = chunk_split(base64_encode($str), 76, $this->LE);
              break;
          case "7bit":
          case "8bit":
              $encoded = $this->FixEOL($str);
              if (substr($encoded, -(strlen($this->LE))) != $this->LE)
                $encoded .= $this->LE;
              break;
          case "binary":
              $encoded = $str;
              break;
          case "quoted-printable":
              $encoded = $this->EncodeQP($str);
              break;
          default:
              $this->SetError($this->Lang("encoding") . $encoding);
              break;
        }
        return $encoded;
    }
