That's the thing — normally at first sight you might recognize "И" as mirrored "N". However when you're used to reading Cyrillic alphabet, you see it as "И" at first and only later realize that it's mangled Latin. Given enough similar looking characters, it becomes hard to read. This doesn't work all the time, e.g. if a word has a single "Я" ("ya") in place of "R", it's usually easy to read. Your milage may vary. Speaking of keyboards, how the hell do they think this product would be sold in countries where there are two sets of alphabets on keyboards if it already comes prefilled with nonsense characters? :)
