title: why cannot filter records with ~ symbol in excel
body: <p>I have a list of record and I want to filter out those records that contain "~6". The problem is....
  I can only filter if it is "~(space)6" but not "~6". When I try to filter "~6", I get the same list of result as when I filter  the results which contain 6. I have been trying for whole day and has no idea what is wrong. Anyone can help? Thank a lot. 
  Here is example data : </p>
  
  <ul>
  <li>~6</li>
  <li>jhjh ~3</li>
  <li>dfdf~6</li>
  <li>dfdfd6dfdfd</li>
  <li>fgfg~6 fdfdd</li>
  </ul>
  
  <p>Here is the result I want if I filter the records that contain ~6</p>
  
  <ul>
  <li>~6</li>
  <li>dfdf~6</li>
  <li>fgfg~6 fdfdd</li>
  </ul>
