title: Topic targeting keywords with commas split into two keywords during validation
body: <p>When searching for keywords and keyword suggestions, there are some keywords that facebook returns, such as "<strong>#Dude, Where's My Car?</strong>" that have commas in them. While trying to validate them, these keywords get split in two. I've tried a number of things from slashes to urlencode to keep them from getting separated, but I haven't been successful. Anyone have any ideas?</p>
  
  <p>The below url part returns valid for every keyword but not for <code>%23Dude%2c+Where%27s+My+Car%3f</code></p>
  
  <pre><code>search?type=adkeywordvalid&amp;keyword_list=Hey+Dude+Wheres+My+Car,Dude+Where+Is+My+Car,Dude+Wheres+My+Car,%23Dude%2c+Where%27s+My+Car%3f,Dude+Wheres+My+Car+Then,Dude+Where039s+My+Car,%23The+Hangover,%23Harold+%26+Kumar+Go+to+White+Castle
  </code></pre>
