Sort a view by country - according to the translated countries

I have a view displaying some nodes of a content type. Each node has a location assigned (with the location module).

I want to group and sort the results by countries. The grouping works fine, and the sorting is almost fine too.

It does sort by country, but it does it using the english countries' names.

However, my website is in french, so I want it to sort using the french countries' names.

Most of the countries are fine, but some are not the same. For example: South Korea is Corée du Sud in french, so it's not the same order.

Views uses the english name to sort, I want it to use the current language (here french, but it's a multilingual website, so also english when it is).
