Decodes the User-Agent header in your Rack request hash to be UTF-8. Mostly useful for headers like

User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; Telecomunicaciones espa��olas`

which get inserted by (rather clueless) telcos, especially in packaged Android distributions (one of the many reasons why letting telcos customize the handset is a bad idea). This library will do it's best to reencode the header in good UTF-8, and barring that will do a lossy replacement with question-mark substitions.

Installation

Add this line to your application's Gemfile:

gem 'sanitize_user_agent_header'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sanitize_user_agent_header

In Rails the gem will be inserted into your application stack automatically. In raw Rack, install the middleware in config.ru like so:

use SanitizeUserAgentHeader

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
