Saving Russian text to a file?

[Bruce Pokras]

I have a desktop app for Mac OS X and Windows that will display Russian text in a field without any problem. However, I have a user in Russia who would like to be able to save that text to a file. My attempts have mainly resulted in question marks where the Cyrillic characters are supposed to be. Is there a particular way in which I should be saving the text to file?

Thanks.
