gem install iso_country_codes
IsoCountryCodes pulls its data from the Wikipedia ISO 3166-1 tables (en.wikipedia.org/wiki/ISO_3166-1), combined with a small number of overrides contained in the ‘overrides.yml` file. For example, the country name of TWN is overridden to “Taiwan” from “Taiwan, Province of China”, to make it less politicised.
The format of the ‘overrides.yml` file is the 3-letter alpha country code as the key, and the fields one wants to override as follows:
"TWN": :name: "Taiwan"
