title: base64 encoding that doesn't use "+/=" (plus or equals) characters?
body: <p>I need to encode a string of about 1000 characters that can be any byte value (00-FF).  I don't want to use Hex because it's not dense enough.  the problem with base64 as I understand it is that it includes + / and = which are characters I can not tolerate in my application.</p>
  
  <p>Any suggestions?</p>
