> I want to change font of alert to some Cyrillic font?
You don't, because the notion of a Cyrillic font is outdated and no longer makes
any sense. Font that come with Mac OS X are Unicode fonts, and as a result they
support not only latin and cyrillic alphabets, but also many others.
You need to use Unicode text in your alert and then you will get Cyrillic
characters.
