strip_control_chars

== Strip Control Chars

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.

=== Examples

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

=== Installation

1. On rails 2.3

• gem install strip_control_chars

• add the following to your environment.rb

  config.gem 'strip_control_chars', version => "1.0"

2. On rails 3

• gem install strip_control_chars

• add the following to your Gemfile

  gem 'strip_control_chars', ">=2.0"

=== Compatibility

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.

=== Caveats

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.
