Kotlin - Form feed character - Illegal escape: '\f'

`Kotlin` does not support the escape `"\f"` (Form Feed Character). So what is the proper way port `"\f"` from `java` to `Kotlin`?

Java:

String str = "\f"; // OK

Kotlin:

var str = "\f" // Illegal escape: '\f'

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

Use unicode escape `\u000C`. [Kotlin doesn't support the `\f` escape.](

) It isn't very widely used. - in fact I didn't realize that there is `\f` in Java until seeing your question.

I made a table on the Java and kotlin escape sequence:
<pre>
Escape type|kotlin |java
\uXXXX yes yes
\XXX no yes // this is Java octal escape.
\t yes yes
\b yes yes
\n yes yes
\r yes yes
\f no yes
\' yes yes
\" yes yes
\\ yes yes
\$ yes no // Java just uses $
</pre>
(Kotlin needs the escaped $ because [string templates][1] use $.)
