title: how to store string with hexadecimal character to environment variable and then retrieve in ruby?
body: <p>How can I save a string with hexadecimal values to environment variable and later retrieve it in ruby?</p>
  
  <p>Currently, when I retrieve it using <code>ENV[]</code> it will return with slashes escaped. So it retrieves like <code>"\\x12\\x33"</code>. How can I make it so that when the environment variable is retrived from ruby then it returns the same exact string <code>"\x12\x33"</code>.</p>
  
  <p>Suppose I have a string with hexadecimal characters such as </p>
  
  <pre><code>s = "\x12\x33"
  </code></pre>
  
  <p>I appreciate any help! Thanks!</p>
