the JSON file to add country name variations is here: tests/testthat/country_name_known_variations.json

Note that this file should only have unambiguous country name variations. For example, this file should not include "Korea" as a variation for "South Korea" because that could also be interpreted as "North Korea".

For reference, this is probably going to remain open as this should be an ongoing process.

• Germany East
• Germany West
• Korea North

• "Virgin Islands (U.S.)" for "Virgin Islands, U.S."

1. Is this test broken now that the default country names have possibly changed since the switch to CLDR names?
2. This is technically only testing English names, correct? Maybe that should be very explicit so we know that we are not testing variations in other languages that we support (only German at the moment).

I fixed all the tests for clrd already.

Being explicit is always good...
