title: Prevent each word from being a single character with Regex
body: <p>I've been checking strings with this regex until now.</p>
  <p><code>^[a-zA-ZöÖşŞçÇüÜıİğĞ.]{1,}(?:\s{1}[a-zA-ZöÖşŞçÇüÜıİğĞ.]{1,})+$</code></p>
  <p>This is a regex that allows the following examples.</p>
  <ul>
  <li>Apple Banana</li>
  <li>A Banana</li>
  <li>A. Banana</li>
  <li>Apple B
  etc...</li>
  </ul>
  <p>But I want prevent both word from being single charackter like this.</p>
  <ul>
  <li>A B</li>
  </ul>
  <p>For example</p>
  <ul>
  <li>A Banana =&gt; This is ok.</li>
  <li>Apple B =&gt; This is ok.</li>
  <li>A B =&gt; This is NOT ok.</li>
  </ul>
  <p>How can I handle it?</p>
