Unicode character in dynamic segment crashes app

[joanniclaborde]

Given this redirects.js file:

module.exports = [{
  from: /\/career(.*)/,
  to: 'http://site.com/career{0}'
}];

And this request: /careers/venture-capital-funding-increased-in-2010-%E2%80%93-but-still-remains-well-below-2007-levels/

This error happens:

The redirect URL should contain encoded characters. Also, does this happen with resources too?
