As an example, Australia wants one. I can't remember if Geneva or Vienna type or both. Last time I've been there was 2019 and my country uses the Latin alphabet too (it was invented here.) The official document is the country's of origin driving license but basically owning a valid IDP states that your country and the destination country are signatories of one of those two conventions and agree to let their own citizens drive in both countries with no need of further tests.
Some countries recognize some foreign driving licenses, at least for a while, without the need of the IDP. The USA is one of them but it has been a long time since I drove a car there so it could have changed or be regulated state by state and not at federal level. The USA is a signatory of the 1949 Geneva convention.
