Yes, that's the most important thing. We dodged a bullet there. Even if Erdoğan's government starts asking English-language writers to switch to "İstanbul" we would need to decline, since Zone names like Europe/Istanbul are in ASCII. As for commentary and auxiliary uses, Rule names (which are private to the database) have always been ASCII so "Türkiye" is dubious there, though I suppose we could change to "Turk" if needed to avoid unnecessary controversy about spelling "Turkey" vs "Turkiye". Also, iso3166.tab has the usual English spelling not the official UN spelling - for example, "Cape Verde" not "Cabo Verde" even though the UN spelling changed in 2013, so to treat "Türkiye"/"Turkey" consistently with "Cabo Verde"/"Cape Verde" we should wait a few years and see what happens.
