[Bug 1408639] Re: Use ISO 4217 standard for displaying currency in the app price

 

Hi Michał, thanks for your report.

When building this feature we initially used just ISO 4217 currency
codes, but got requests from our US devels to use the "$" symbol
instead, because they are not used to see the "USD" code in websites.

But using the "$" symbol presents a problem when using this in a country
where it means a different thing. Say, "Mexican Peso" or "Australian
Dollar". In those cases, users would be expecting to be charged in their
home currency, and would be surprised to find a charge in USD in their
credit card bill.

A different option is using the "long symbol" form (eg: US$), as defined
in the unicode standard:
http://www.unicode.org/cldr/charts/26/summary/root.html#2976

Our US devels found it more acceptable, since it's a bit more common to them to see US$ than USD, so we ended up using symbols or long symbols for a handful for currencies, and ISO codes for the rest:

Title:
  Use ISO 4217 standard for displaying currency in the app price

Bug description:
  Recently on Google Plus, Michael Hall published an image with his paid app(1). I'm basing this bug report on that image and comments under MIchael's post(2).
  You can see there's „US$2.99” text on the button and under his name. „US$” is not a valid currency code according to ISO 4217 standard(3). It is rather a currency symbol(4). 
  In the G+ comments Michael mentioned there are also „EUR” and „GBP”. They both are currency codes.

  It would be nice if only one system was used consequently in the
  Ubuntu Store across all possible currencies. I'm all for using ISO
  4217 standard.
