I made the same (offline first, very small, vector based) but with a focus on i18n. So it's available in all languages of the United Nation (except Spanish because I just forgot, shame on me, could be made in a couple of hours).
The name of the countries (and cities) are the official one declared at the UN. So, yeah, the official short version of UK is "United Kingdom of Great Britain and Northern Ireland".
