Rails 3 - Multiple Currencies

If I do this:

number_to_currency(100,:locale=>'en-GB')

I'd expect to get something like this:

£100.00

But instead I'm getting

$100

This is the same if I pass in the locale :en, 'fr-FR' or whatever.

Does Rails have a default list of currencies based on locale, or do I have to setup the I18 mappings for every country on the planet myself?

Any help appreciated.

In the locale file, the currency unit is defined via

number:
  currency:
    unit:    "$"

You have to do it yourself. This may help:
