string wolfGetAgentCountry(string agent)

The country the avatar `agent` (root or child presence in this region) is connected from, as an upper-case ISO 3166-1 alpha-2 code ("GB", "DE") from the region's local IP-to-country database - never the address. "" for a non-avatar key, an NPC, a region without the database, an avatar on a WolfStorm proxy host, or an address with no country in the database (wolfGetLastError says which). Defined on Wolf_Api.wolfGetAgentCountry / WolfGeoCountry.

The country an avatar is connected from, as a two-letter code in capitals (ISO 3166-1 alpha-2): "GB", "DE", "US". Use it to greet visitors, or show a poster or a terminal, in a language they are likely to read. The region looks the address up in its own country database: the address never leaves the region, and your script never sees it. It is where the connection comes from, not where someone lives or which language they speak - a VPN or a mobile network can put them anywhere. Returns "" for a key that is not an avatar here, an NPC, a region without the country database, an avatar using WolfStorm (the region sees the WolfStorm server's address, not theirs), or an address the database has no country for, with wolfGetLastError saying which.
