title: Find the first character in a string that is a letter
body: <p>I am trying to figure out how to look through a string, find the first character that is a letter and then delete from that index point and on.</p>
  <p>For example,</p>
  <pre><code>string test = &quot;5604495Alpha&quot;;
  </code></pre>
  <p>I need to go through this string, find <code>&quot;A&quot;</code> and delete from that point on.</p>
