No underscore/dash escaping in Mongoid

mongoid.rb

# Disables converting '-' and '_' into '-dash-' and '-undscr-' during composite key generation
class String
  def identify
    if Mongoid.parameterize_keys
      key = ""
      each_char { |c| key += ((c != '_' && c != '-' && CHAR_CONV[c]) || c.downcase) }; key
    else
      self
    end
  end
end

only this version (https://gist.github.com/749649/87ae99a47430846d2854aae63192d4704c423b71) working properly for turkish charset ( Öö Çç Üü Şş Iı İi Ğğ)
