title: How to escape the < and ≤ symbols in xml?
body: <p>I want to create a string <code>&lt;res&gt;</code> in android as below:</p>
  
  <pre><code>&lt;string name="bmi0"&gt;0: BMI≤18.5&lt;/string&gt;
  &lt;string name="bmi1"&gt;1: 18.5&lt;BMI≤24&lt;/string&gt;
  &lt;string name="bmi2"&gt;2: 24&lt;BMI≤27&lt;/string&gt;
  </code></pre>
  
  <p>But i shown the error of "Tag start is not closed". </p>
  
  <p>I tried to put a <code>\</code> symbol in front, but it doesn't work, it has shown the same error.</p>
  
  <pre><code>&lt;string name="bmi0"&gt;0: BMI\≤18.5&lt;/string&gt;
  &lt;string name="bmi1"&gt;1: 18.5&lt;BMI\≤24&lt;/string&gt;
  &lt;string name="bmi2"&gt;2: 24&lt;BMI\≤27&lt;/string&gt;
  </code></pre>
  
  <p>How to escape the special XML symbols ?</p>
