Kotlin - Form feed character - Illegal escape: '\f' : <p><code>Kotlin</code> does not support the escape <code>"\f"</code> (Form Feed Character). So what is the proper way port <code>"\f"</code> from <code>java</code> to <code>Kotlin</code>?  </p>

<p>Java: </p>

<pre><code>String str = "\f"; // OK
</code></pre>

<p>Kotlin:</p>

<pre><code>var str = "\f"  // Illegal escape: '\f'
</code></pre>

<p>Anyway, that looked like a bug to me because Kotlin and java should work well together. </p>
