Check if a Char represents a non-character codepoint in Kotlin

In C++ Qt framework, Qchar type has method named isNonCharacter() which Returns true if the QChar is a non-character. Is there any similar method for Kotlin Char type.

Kotlin provides a Char.isDefined() extension method that seems to do just what you want (or at least, the direct opposite).

So you can do e.g.:

val c = 10000.toChar()
if (!c.isDefined())
    throw Exception("Char is not defined")

(This function is available in Kotlin/JVM and Kotlin/Native, but not in Kotlin/JS yet.)
