Hi Ravi,
Please provide more details about the type of questions you are trying to import into your Lesson instance. If you could attach to your reply the file which you are trying to import it would be much easier for us to understand your problem and suggest a solution.

Eric "I am using the same process I used to build a 500-page course all in Russian -- even in the course's main page the title of the survey appears as ????."
From what you say it appears that your character problem is not specific to the Questionnaire module. If you could display Cyrillic text in the other parts of your moodle site / courses, then it would display OK in the Questionnaire module too.
Maybe re-post your question in the General problems or the Languages forums.
