title: Is there a Unicode character for plus over minus? (+/-)
body: <p>Occasionally I've seen the symbol "plus or minus" written in fractional form, like this:</p>
  
  <p><img src="https://i.stack.imgur.com/oke8m.jpg" alt="plus or minus"></p>
  
  <p>Is there a Unicode character for this?</p>
  
  <p><strong>Note:</strong> I already know about the <a href="http://www.fileformat.info/info/unicode/char/b1/index.htm" rel="noreferrer">standard "plus-minus sign" symbol</a>, but it won't work in this context. I'm specifically looking for a version with the fraction bar.</p>
