Rack middleware to remove invalid UTF-8 characters from the environment so that your app doesn't choke on them. Prevents errors like "invalid byte sequence in UTF-8".

Add this line to your application's Gemfile:

gem 'utf8-cleaner'

If you're not running Rails, you'll have to add the middleware to your config.ru:

require 'utf8-cleaner'
use UTF8Cleaner::Middleware

There's nothing to "use". It just works!

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request
