title: How to encode cyrillic characters for URL and then decode them?
body: <p>I have a form on one page:</p>
  
  <pre><code>&lt;form method="POST" accept-charset="UTF-8" action="index.cgi" name="TestForm"&gt;
  </code></pre>
  
  <p>One of the input fields "search_string" may be used to send Cyrillic characters and if that happens the URL string looks like this:</p>
  
  <pre><code>search_string=%41F%2F%424+%41F%41E%414%416%410%420%41A%410+%418%417+%421%412%418%41D
  </code></pre>
  
  <p>How do I decode this back to the original string on the page I post to?</p>
