Get Currency symbol of only one character (e.g $,₹, etc) (Locale doesn't matter) android kotlin

i have currency code (e.g. USD,INR,etc...). I want to get symbols of only one letter of those codes (e.g $,₹, etc). i have tried to find many solutions like this but it doesn't works for me. i am using code as below 

var pound = Currency.getInstance("GBP");
var symbol = pound.getSymbol();

but it returns symbols like (Rs., US$, AU$, etc...). i want to get only one character symbol as mentioned above. i know that symbols are dependent on their locale but i want to get symbols independent from their locale.

To answer your question quickly in Kotlin:

var pound = Currency.getInstance("GBP");
val symbol = pound.symbol
println(symbol) // prints £

In case useful, I paste my solution to get currency code (i.e.: EUR) and currency symbol (i.e. €) and :

val locale = Locale.getDefault()
val numberFormat = NumberFormat.getCurrencyInstance(locale)
println(numberFormat.currency)  // on my device in Italy prints: EUR

val symbol = numberFormat.currency?.symbol
println(symbol) // on my device in Italy prints: €

I simply created this kotlin extension function which isolates the currency symbol if there is one or uses the provided symbol if there isn't one.

// Supply the Currency Symbol, e.g. US$, would return $ and IDR would return IDR
fun String.isolateCurrencySymbol(): String{
    for (char in this){
        if (char !in CharRange('A', 'Z')){
            return char.toString()
        }
    }
    return this
}

This works fine for me

import android.os.Build

import android.support.v7.app.AppCompatActivity
import android.os.Bundle

import kotlinx.android.synthetic.main.activity_main.*
import java.util.*

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        count()
    }

    fun count () {
        val pound = Currency.getInstance("USD")
        var str:String
        str = if(Build.VERSION.SDK_INT >=24) pound.getSymbol(Locale.getDefault(Locale.Category.DISPLAY))
        else pound.getSymbol(resources.configuration.locale)
        tvText.text = str
    }


}

try to calling default Locale in getSymbol() like getSymbol(Locale.getDefault(Locale.Category.DISPLAY)) check below code

Currency pound = Currency.getInstance("GBP");
pound.getSymbol(Locale.getDefault(Locale.Category.DISPLAY));
