Does Checkout support purchases in multiple currencies?

For the list of currencies that Stripe supports, go to https://support.stripe.com/questions/which-currencies-does-stripe-support.

When you sign up for Stripe, you choose a default payment currency based on your country (for example, USD if you’re in the United States). You can enable other currencies in your Stripe account settings. When customers purchase your app or component, Checkout charges them in your specified currency and deposits the money into your bank account.
