Exporting Ruby CSV from ActiveRecord single quote in Excel looks weird

Question

When I open the exported CSV file from Excel after extracting data from my table using the Ruby's CSV library . I open the file using Excel (all of my users use Excel to open my CSV files). It comes out funky looking. Here's some screen shots.

I tried converting converting it to ASCII, but I get an error: Encoding::UndefinedConversionError: U+2019 from UTF-8 to US-ASCII

CSV.open(fileNameInbound, 'wb', :encoding => Encoding::US_ASCII) do |csv| 
  myModel.all.each do |m| 
    csv << m 
  end 
end

In Excel looks like this:

I fixed my problem by adding BOM characters in the beginning of my file to force the UTF-8 in Excel.

CSV.open(fileNameInbound, 'wb', encoding: 'UTF-8') do |csv| 
  myModel.all.each do |m| 
    csv << ['\xef\xbb\xbf']
    csv << m 
  end 
end
