What does it do?

This extension provides Italian translations for the country, country subdivision, currency, language and territory records of static_info_tables. For this purpose, it adds one or two fields to those tables and fills them with Italian data, if available. The data is based on World countries in JSON, CSV, XML and YAML (mledoze/countries) https://github.com/mledoze/countries#world-countries-in-json-csv-xml-and-yaml. This is mostly the same as Debian ISO Codes https://salsa.debian.org/iso-codes-team/iso-codes which is used in TYPO3 since version 12.
