title: checking unicode with special characters
body: <p>I have unicode strings like </p>
  
  <p><code>u'0d7a6b6b37682bab6d8eda97cda4bad7'</code> </p>
  
  <p>and </p>
  
  <p><code>u'Brauers, A.'</code></p>
  
  <p>I would like to distinguish between two of these. I tried using <code>regex</code> with <code>\p{Alphabet}</code> but it does not work with the second example as the second example contains <code>,</code> and <code>.</code>. Can anyone help me with this?</p>
