title: PHPMailer inserts '=' equal sign every 75th character
body: <p>Using PHPMailer 5.2.14, emails are sent in text/html.  The outgoing text is littered with equal signs every 75th character.  </p>
  
  <p>I tried using the <a href="https://github.com/PHPMailer/PHPMailer/issues/464">EOL workaround</a>, but it did not remove the extra equal signs: </p>
  
  <pre><code>$email = new PHPMailer();
  $email-&gt;From      = 'from@example.com';
  $email-&gt;FromName  = 'FromUser';
  $email-&gt;AddAddress( 'to@example.com' );
  $email-&gt;Subject   = 'This is a test';
  $email-&gt;IsHTML(true);
  $email-&gt;Body = "&lt;p&gt;This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; &lt;/p&gt;";
  
  // fix EOL here? 
  $email-&gt;LE = PHP_EOL;
  
  $email-&gt;Send();
  </code></pre>
  
  <p>Resulting source upon receipt:</p>
  
  <pre><code>&lt;meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"&gt;&lt;font face="arial"&gt;&lt;base href="http://example.com/"&gt;&lt;!-- &lt;/base&gt; --&gt;=
  &lt;p&gt;This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This i=
  s a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.=
  &amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; Th=
  is is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a t=
  est.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp; This is a test.&amp;nbsp;=
   &lt;/p&gt;&lt;/font&gt;
  </code></pre>
  
  <p>The equal signs appear when viewing in Outlook.    When I send the same text/html to a gmail account, the equal signs are not present.  </p>
  
  <p>What needs to happen to eliminate these stray equal signs for recipients using Outlook? </p>
