title: How to remove redundant spaces/whitespace from a string in Golang?
body: <p>I was wondering how to remove:</p>
  
  <ul>
  <li>All <strong>leading/trailing</strong> whitespace or new-line characters, null characters, etc.</li>
  <li>Any redundant spaces within a string (ex. "hello[space][space]world" would be converted to "hello[space]world")</li>
  </ul>
  
  <p>Is this possible with a single Regex, with unicode support for international space characters, etc.?</p>
