title: Is there a way to use regexp match for characters with tilde?
body: <p>Look at this:</p>
  
  <pre><code>"nAo".match(/(nao)/i) # =&gt; #&lt;MatchData "nAo" 1:"nAo"&gt;
  
  "nÃo".match(/(não)/i) # =&gt; nil
  </code></pre>
  
  <p>is there a way to fix that?</p>
  
  <p>Edit:
  It seems that ruby lacks support for unicode characters on regexp comparisons with i flag(ignore case)...
