title: How to escape special characters in the key of properties file?
body: <p>I've got a <code>key = value</code> property in the .properties file:</p>
  
  <pre><code>give names: (1) code = xxx
  </code></pre>
  
  <p>... but when I tried to get that key, it threw an error:</p>
  
  <blockquote>
    <p>No message found under code give names: (1) code = xxx</p>
  </blockquote>
  
  <p>I tried escaping the whitespace with <code>\</code> but it didn't work.</p>
  
  <p>Do I need to escape <code>:</code>,<code>(</code>, and <code>)</code> characters as well?</p>
