Char

inline fun Char(code: Int): Char(source)

Creates a Char with the specified code, or throws an exception if the code is out of Char.MIN_VALUE.code..Char.MAX_VALUE.code.

If the program that calls this function is written in a way that only valid code is passed as the argument, using the overload that takes a UShort argument is preferable (Char(intValue.toUShort())). That overload doesn't check validity of the argument, and may improve program performance when the function is called routinely inside a loop.
