title: Twitter search api request fails with international charcters
body: <p>I'm using the <a href="https://github.com/J7mbo/twitter-api-php/blob/master/TwitterAPIExchange.php" rel="nofollow">TwitterAPIExchange</a> wrapper to retrieve tweets from the twitter search api. It works fine as long as I don't use the sewdish characters å, ä, ö. </p>
  
  <p>My code is simply this:</p>
  
  <pre><code>$url = 'https://api.twitter.com/1.1/search/tweets.json';
  $getfield = '?q='.$twittername.'&amp;lang=sv';
  $requestMethod = 'GET';
  
  $response = $twitter-&gt;setGetfield($getfield)
                  -&gt;buildOauth($url, $requestMethod)
                  -&gt;performRequest(); 
  </code></pre>
  
  <p>When I echo out <code>$twittername</code>, I can see that the name is correct swedish, but in the response from twitter the query that twitter receives is using replacement characters. For example: A request for the name <code>Göran</code>, becomes <code>G%EF%BF%BDran</code>. </p>
  
  <p>I have set my datbase to utf-8 general.</p>
  
  <p>I have also tried to urlencode the characters å, ä, ö (with <code>%E5</code>, <code>%E4</code>, <code>%F6</code> ), but the query that twitter receives remains the same, ie <code>G%EF%BF%BDran</code>.</p>
