Hello,
With a current update to iso3166 multiple communities are having issues due to looking up country codes with special characters:
For example Åland Islands, Türkiye. While we could just use the alphacode it would be nice to still be able to pass into non-accented English spellings of the country (Aland Islands, Turkey) as an alpha4 in the tuple to allow for backward compatibility. I can get a PR going for this if you need it.
