How about a method that converts a String to its binary form (i.e 0s and 1s)

fun main(args: Array<String>) {
    println("foo".binaryRepresentation())
}

fun String.binaryRepresentation(): String {
    val bytes = toByteArray()
    val binary = StringBuilder()
    for (b in bytes) {
        var save = b.toInt()
        for (i in 0 until Byte.SIZE_BITS) {
            binary.append(if (save and 128 == 0) 0 else 1)
            save = save shl 1
        }
        binary.append(' ')
    }
    return binary.toString()
}

I do not know if there is something in the stdlib that can do it though...

That is the output by the way
01100110 01101111 01101111

Or is there a simple way to do it

[karelpeeters]

What's the use case?

[Aregev2]

None, just found it interesting... 🤷

[karelpeeters]

But yeah there's a way easier solution, give me a sec.

fun String.binaryRepresentation() = toByteArray().joinToString(" ") { it.toString(2).padStart(8,'0') }
