Returns a 400 error when there are invalid UTF-8 characters in the environment so that your app doesn't choke
on them. This prevents errors like "invalid byte sequence in UTF-8".

## Installation

Add this line to your application's Gemfile:

```ruby
# Gemfile
gem 'utf8_gatekeeper'
```

And then execute:

```
bundle
```

Or install it yourself as:

```
gem install utf8_gatekeeper
```

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

```ruby
# config.ru
require 'utf8_gatekeeper'
use UTF8Gatekeeper::Middleware
```

## Usage

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