Rails views [escape strings by default](http://yehudakatz.com/2010/02/01/safebuffers-and-rails-3-0/). Jbuilder has nothing to do with it:
```ruby
Jbuilder.encode{ |j| j.foo 'bar' } # => "{\"foo\":\"bar\"}"
```

You can put any string containing quotes or any non html-safe entities and see that they'll be escaped.
