thank you for this information, it helps to know that there's an explanation for my problem. though I'm not sure what to do with it. I tried copying the text of a file from an old Wordperfect for Mac OS 9 document into a new Word document in OS X, and then tried saving it using a font ending in CY, but that didn't do anything. The cyrillic portion of the text still appears as gibberish. I also tried to open Appleworks, which seems to be part of Microsoft Office, but I couldn't figure out what to do. Could you please be more specific in your suggestions of what I should try to do? Sorry to be boneheaded, I'm obviously not a computer whiz.
