Declaring Byte in Kotlin does compile-time error 'The integer literal does not conform to the expected type Byte'

Question

As seen another question in 0xFF0000FF An integer literal does not conform to the expected type kotlin.Int

I declaring value 0xFF as Byte

val b:Byte = 0xFF

receiving The integer literal does not conform to the expected type Byte compile error

Since I have clue about kotlin.Byte is signed byte

How to declaring Byte in Kotlin with 0x00 - 0xFF unsigned byte just like .net Byte b = 0xFF ?

If you want instant compiler for testing and answer:

Kotlin doesn't automatically convert between number types.

If you do val b:Byte = 0xFF.toByte() then it compiles and results in a byte with value -1.

If you want to hold the unsigned byte value then you need to store it as a Char, but you will need to convert it to another type to print it as a number:

val b = 0xFF.toChar()
println(b.toInt())
