Only two-letter country codes are supported, since these are the only ones that were freely available from the ISO 3166 standard. However, as of 2015-01-09, even these are no longer freely available in a machine readable format.

This script also knows about non-geographic, generic, USA-centric, historical, common usage, and reserved top-level domains.
