Non-English texts in Stripe possible?

Question

Successfully integrating Stripe into my online shop, I completely failed to get information on whether/how to configure Stripe to return error messages in German instead of Eng

For further reference:

While you can't use human messages on stripe errors to be displayed directly on localized pages, you can take advantage of response.error.code to provide your own translations.

    var errorMessages = {
      incorrect_number: "The card number is incorrect.",
      invalid_number: "The card number is not a valid credit card number.",
      invalid_expiry_month: "The card's expiration month is invalid.",
      invalid_expiry_year: "The card's expiration year is invalid.",
      invalid_cvc: "The card's security code is invalid.",
      expired_card: "The card has expired.",
      incorrect_cvc: "The card's security code is incorrect.",
      incorrect_zip: "The card's zip code failed validation.",
      card_declined: "The card was declined.",
      missing: "There is no card on a customer that is being charged.",
      processing_error: "An error occurred while processing the card.",
      rate_limit:  "An error occurred due to requests hitting the API too quickly. Please let us know if you're consistently running into this error."
    };


    function stripeHandler( status, response ){
      if ( response.error && response.error.type == 'card_error' ){
        $( '.errors' ).text( errorMessages[ response.error.code ] );
      }

      else {
        // do other stuff (and handle api/request errors)
      }
    }

The list of codes is documented here (currently, right column, in the "codes" section).
