title: UTF-8 and upper()
body: <p>I want to transform UTF-8 strings using built-in functions such as upper() and capitalize().</p>
  
  <p>For example:</p>
  
  <pre><code>&gt;&gt;&gt; mystring = "işğüı"
  &gt;&gt;&gt; print mystring.upper()
  Işğüı  # should be İŞĞÜI instead.
  </code></pre>
  
  <p>How can I fix this?</p>
