Some problems with converting char array to string

Question

Good day, I'm starter and I have some problem:

I want to convert this "ромка" or this "роМка" to "Ромка" using this code. My code is OK. I have problem with toString().

Rewrite string using only one first upper char. Problem with converting charArray to String

var name = "ромка"
var charName = name.toLowerCase().toCharArray()
charName[0] = charName[0].toUpperCase()

name = charName.toString()

Results:

charName: {'Р', 'о', 'м', 'к', 'а'}

name == "[C@93ec54"
