Currency conversion from 3 character code (USD) to their symbol as output ($) in magento 2?

Question

Does magento 2 is having something inbuilt function for currency symbol getting ?
What I want is - Input will be 3 characters currency code as USD, INR, JPY, EUR etc. corresponsing to that output should be $ , ₹ , ¥ etc...
All the solutions are appreciated even if its inbuilt in magento 2 or custom function or some API.

At the position echo $ocd; it gives me USD after that I need to print $, it may give Euro then I need to echo € and so on..

$detail_query_1="SELECT a.quote_id,a.entity_id,a.state,a.status,a.coupon_code,a.shipping_description,a.order_currency_code,a.discount_amount,a.customer_id,a.base_discount_amount,a.base_grand_total,a.base_shipping_amount,DATE_FORMAT(a.created_at,'%d-%m-%Y') AS order_date,a.total_item_count,b.increment_id FROM rpt_sales_order AS a JOIN rpt_sales_order_grid AS b ON a.entity_id=b.entity_id WHERE 1 AND b.increment_id='$ids'";
 //echo $detail_query_1;//exit;
 $sql_detail_1=mysqli_query($con,$detail_query_1) or die(mysqli_error($con));
 if(@mysqli_num_rows($sql_detail_1))
 { 
  $cnt1=@mysqli_num_rows($sql_detail_1);
  while($rt_details_1=mysqli_fetch_array($sql_detail_1,MYSQLI_ASSOC))
  {
   #print_r($rt_details);exit;
   $ordDt=$rt_details_1['order_date']; 
   $shpDesc=$rt_details_1['shipping_description']; 
   $ocd=  $rt_details_1['order_currency_code'];
   echo $ocd;
   $discount_amount=  $rt_details_1['discount_amount'];
  }

echo '<h3 class="shipping-method">Shipping Method: '.$shpDesc.'</h3>';
 }

1. Set your symbol currency from admin settings Store -> Currency -> Currency Symbols

As per you question try below code

$currency = $_objectManager->create('Magento\Directory\Model\CurrencyFactory')->create()->load($currencyCode);
$currencySymbol = $currency->getCurrencySymbol();

As per your requirement, Add this code in php file at Magento root folder and run through Magento URL. For example: You file name script.php and run magentostore.com/script.php

<?php
use Magento\Framework\App\Bootstrap;
require __DIR__ . '/app/bootstrap.php';
 
$bootstrap = Bootstrap::create(BP, $_SERVER);
$objectManager = $bootstrap->getObjectManager();
 
$state = $objectManager->get('Magento\Framework\App\State');
$state->setAreaCode('frontend');
 
$currencyCode = 'your_code';
$currency = $objectManager->create('Magento\Directory\Model\CurrencyFactory')->create()->load($currencyCode);
echo $currencySymbol = $currency->getCurrencySymbol();

?>
