title: Removing all whitespace characters except for " "
body: <p>I consider myself pretty good with Regular Expressions, but this one is appearing to be surprisingly tricky:  I want to trim <strong>all</strong> whitespace, <strong>except</strong> the space character: <code>' '</code>.</p>
  
  <p>In Java, the RegEx I have tried is: <code>[\s-[ ]]</code>, but this one also strips out <code>' '</code>.</p>
  
  <p><strong>UPDATE:</strong></p>
  
  <p>Here is the particular string that I am attempting to strip spaces from:</p>
  
  <pre>project team                manage key</pre>
  
  <p>Note: it would be the characters between "team" and "manage".  They appear as a long space when editing this post but view as a single space in view mode.</p>
