title: Regex, Forbid dot (.) as a the last character
body: <p>Does anybody knows how to write Regex for condition: "Dot is not allowed as the last character".
  My Regex is:  </p>
  
  <pre><code>"^[0-9A-Za-z!$'( )+,-;=@\\[\\]_`^]+$"
  </code></pre>
  
  <p>How can I cover the condition: 
  <em>Name.png</em> (<strong>is allowed</strong>)   <em>VS</em>  <em>Name.</em><strong>(**is forbbiden</strong>)</p>
