title: Where can I get a list of Unicode chars by class?
body: <p>I'm new to learning Unicode, and not sure how much I have to learn based on my ASCII background, but I'm reading <a href="http://msdn.microsoft.com/en-us/library/aa664670(VS.71).aspx" rel="noreferrer">the C# spec on rules for identifiers</a> to determine what chars are permitted within <a href="http://msdn.microsoft.com/en-us/library/dd179338.aspx" rel="noreferrer">Azure Table</a> (which is directly based on the C# spec).</p>
  
  <p>Where can I find a list of Unicode characters that fall into these categories:</p>
  
  <ul>
  <li><code>letter-character</code>: A Unicode character of classes Lu, Ll, Lt, Lm, Lo, or Nl</li>
  <li><code>combining-character</code>: A Unicode character of classes Mn or Mc</li>
  <li><code>decimal-digit-character</code>: A Unicode character of the class Nd</li>
  <li><code>connecting-character</code>: A Unicode character of the class Pc </li>
  <li><code>formatting-character</code>: A Unicode character of the class Cf  </li>
  </ul>
