I don't know if there is an automatic way to do it.
I would:
1. Query DB to get your records
2. Perform character replacement on each record as you pull from the db (change "," to "~" or something else odd you know wouldn't be used otherwise)
3. Add record to CSV file
Then do the same thing backwards.
Or, change the comma to its UTF-8/ASCII/URL-Encoded equivalent or something like that.
