What is a proper replacement for the now-deprecated <http://io.ktor.utils.io|io.ktor.utils.io>.core.String constructor here?
I need to decode ASCII.

You can create a decoder with Charsets.ISO_8859_1.newDecoder() to decode a Source into a string. Here is an example:

val bytes = ByteArray(1024) { 65 }
val buffer = Buffer()
buffer.write(bytes)
val string = Charsets.ISO_8859_1.newDecoder().decode(buffer)

Can I cache and reuse "Charsets.ISO_8859_1.newDecoder()" ?

[Aleksei Tirman [JB]]

Yes, you can.

So this is safe?

private val decoder = Charsets.ISO_8859_1.newDecoder()

internal actual fun ByteArray.decodeLatin1BytesToString(): String {

    val buffer = Buffer()
    buffer.write(this)

    return decoder.decode(buffer)
}

[Aleksei Tirman [JB]]

It should be safe

Thank you for your help! 🙂
