title: What is "=C2=A0" in MIME encoded, quoted-printable text?
body: <p>This is an example raw email I am trying to parse:</p>
  
  <pre><code>MIME-version: 1.0
  Content-type: text/html; charset=UTF-8
  Content-transfer-encoding: quoted-printable
  X-Mailer: Verizon Webmail
  X-Originating-IP: [x.x.x.x]
  
  =C2=A0test testing testing 123
  </code></pre>
  
  <p>What is =C2=A0?  I have tried a half dozen quoted-printable parsers, but none handle this correctly.  <strong>How would one properly parse this in C#?</strong></p>
  
  <p>Honestly, for now, I'm coding:</p>
  
  <pre><code>//TODO WTF
  encoded = encoded.Replace("=C2=A0", "");
  </code></pre>
  
  <p>Because I can't figure out why that text is there randomly within the MIME content, and isn't supposed to be rendered into anything.  By just removing it, I'm getting the desired effect - but WHY?!</p>
  
  <p>To be clear, I know that (=[0-9A-F]{2}) is an encoded character.  But in this case, it seemingly represents NOTHING.</p>
