title: is it proper to name the images for Non-English Alphabet language for SEO aims by urlencode() output
body: <ol>
  <li>In Turkish, we call 'şarkı' for 'song'.</li>
  <li><code>urlencode('şarkı') == '%C5%9Fark%C4%B1'</code></li>
  <li>most of users in our country will search for 'şarkı' in image search
  (not for sarki or song)</li>
  </ol>
  
  <p>if I name my image <code>'%C5%9Fark%C4%B1.png'</code> in ftp, Can I be sure that all engines (most popular ones are google, yandex here) will exactly understand that visitor searched for <code>'şarkı'</code> which is matching with <code>'%C5%9Fark%C4%B1.png'</code> at some image search result page?</p>
  
  <p>note: I don't know if it's related however I utilize utf-8 in HTML, php connection language setting and also MySQL tables.</p>
  
  <p>thanks</p>
  
  <p>best regards</p>
