title: What's the correct syntax to filter the MIDDLE DOT Unicode character using a Perl regex?
body: <p>I'm trying to figure out the correct syntax to filter the <a href="http://www.fileformat.info/info/unicode/char/00b7/index.htm" rel="nofollow"><code>MIDDLE DOT</code></a> Unicode character (<code>U+00B7</code>) out of a string and keep the original string</p>
  
  <pre><code>     $_ =~ s/test_of_character (.*[^\x{00b7}])/$1/gi;
  </code></pre>
  
  <p>From the code above, I'm not sure how to keep the original string before removing the middle dot from the string.</p>
