So it is! It seems to even fool Chrome. If you search for "delivered" on the page the search box says "1/4" but entering will only take you to the 2 real ones, not the Turkish i ones which it has presumably counted.
The alternative is worse though. Characters with umlauts matched with characters with no umlauts. E.g. searching for "rõõsa" will find both "rõõsa" and "roosa", incredibly annoying.
