Does that help That cannot work? When your reduce the length, information is lost.
The only thing possible is that you decide not to use the full spectrum of UTF-8. Lets assume you only you 7bit ASCII, This means the first 128 chars from the ASCII table. But that only make a length of 7 from a string of length 8. Maybe a bit more if you take into account the full power of UTF-8.

How to merge Stream<Map<String, Map<String, String>>> into a single Map<String, Map<String, Stri

it fixes the issue I am trying to merge a Stream>> object into a single map with keys in all the Streams. , When you have
Stream<Map<String, Map<String, String>>> stream = ...
.flatMap(map -> map.entrySet().stream())
.collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue));
.collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue, (vOld, vNew) -> ...));
//                                                                                ^^^
Map<String, Map<String, String>> combinedMap = 
        /*your Stream<Map<String, Map<String, String>>>*/
        .flatMap(map -> map.entrySet().stream())
        .collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue));

How can I create Hashmap<String,Int : String,String : String,String> in Kotlin for sorting

this one helps. I assume that chatMessages is of type List. This is generally bad because you cannot to anything with strings. I would suggest you to create a data class which contains all information about a chat message, like so:
data class ChatMessage(val dateTime: Int, val userMail: String?, val userMessage: String?) : Comparable<ChatMessage> {
    override fun compareTo(other: ChatMessage) = this.dateTime.compareTo(other.dateTime)
private val chatMessages = mutableListOf<ChatMessage>()
data class ChatMessage(val dateTime:Int?, val userMail: String?, val userMessage: String?) : Comparable<ChatMessage> {
    override fun compareTo(other: ChatMessage) = this.dateTime.compareTo(other.dateTime)

private val chatMessages = mutableListOf<ChatMessage>()

fun yourCode() {
    newReference.addValueEventListener(object : ValueEventListener {

        /* Use proper variable naming. Nobody will understand, what p0 is, but if you name
        it dataSnapshot, everyone knows at a glance. */
        override fun onDataChange(dataSnapshot: DataSnapshot) {


            // Again, what is ds exactly? Name it properly.
            for (ds in dataSnapshot.child(playerIDmatchWhoIs).children) {
                // Kotlin recommends to use val instead of var.
                // This way, you know that your variables cannot be modified unless you want them to be modified.
                val hashMap = ds.getValue() as HashMap<String, String>

                // use indexing instead of the get() method
                val dateTime = hashMap["datetime"]
                val userMail = hashMap["usermail"]
                val userMessage = hashMap["usermessage"]

                // TODO: Handle null values properly
                chatMessages.add(ChatMessage(dateTime!!.toInt(), userMail, userMessage))



Dotnet Core - Getting a warning on 'string.Replace(string, string?)' saying use 'string.Replace(string, string?, System.

this will help just... tell it what comparison type you want; for example, for an ordinal-ignore-case replace:
    .Replace("and", "&", StringComparison.OrdinalIgnoreCase)
    .Replace("substringof", string.Empty, StringComparison.OrdinalIgnoreCase)
    .Replace("(", string.Empty, StringComparison.OrdinalIgnoreCase)
    .Replace(")", string.Empty, StringComparison.OrdinalIgnoreCase)
    .Replace("'", string.Empty, StringComparison.OrdinalIgnoreCase)
    .Replace(" ", string.Empty, StringComparison.OrdinalIgnoreCase)
    .Replace("eq", ",", StringComparison.OrdinalIgnoreCase);
