Call for Opinion: Method that only returns currency symbol

[izshreyansh]

I'm planning to send a PR that will return currency symbol.

Possible client code might look like this:

currency()->getCurrencySymbol() which outputs one of the relevant currency symbol like: $, €.

I came across this idea while using bootstrap form method to place a prepend on input.

<div class="input-group mb-3">
  <div class="input-group-prepend">
    <span class="input-group-text">$</span>
  </div>
  <input type="number" class="form-control" placeholder="Price" aria-label="Price">
</div>
