It's not really a good for for FasterCSV for the same reason's I

This seems to work:

 >> %Q{,,,,"xyz",,,,}.split(",", -1).map { |f| f.empty? ? nil : f }
=> [nil, nil, nil, nil, "\"xyz\"", nil, nil, nil, nil]

Again, do not set :quote_char and :col_sep to the same value.  That's  
impossible to parse.  Also :force_quotes is only used when writing  
CSV, not reading it.
