At the lower end of the ASCII range are a few control characters that are generally innocent but useless. Often benign, they sometimes jump out and bite you when you're trying to do something simple like generate some XML.
If you model doesn't need them, then remove them before they even make it into your database.
class Product < ActiveRecord::Base strip_control_chars! end class Product < ActiveRecord::Base strip_control_chars!, :except => :title end class Product < ActiveRecord::Base strip_control_chars!, :only => :description end
On rails 2.3
* gem install strip_control_chars * add the following to your environment.rb config.gem 'strip_control_chars', version => "1.0"
On rails 3
* gem install strip_control_chars * add the following to your Gemfile gem 'strip_control_chars', ">=2.0"
On rails 2.x you must use version 1.x of this gem. On rails 3.x you must use version 2.x of this gem.
The translation is done with raw bytes. If you happen to be using anything other than UTF-8 in your models, you're likely to munge data.
This also means it's almost certainly not ruby 1.9 compatible. Patches welcome.
