Why does Rails titlecase add a space to a name?

Question

Why does the titlecase mess up the name? I have:

John Mark McMillan

and it turns it into:

>> \"john mark McM         


        

Answer 1

If all you want is to ensure that each word starts with a capital:

class String
  def titlecase2
    self.split(' ').map { |w| w[0] = w[0].upcase; w }.join(' ')
  end
end

irb(main):016:0> "john mark McMillan".titlecase2
=> "John Mark McMillan"
