now-env-pull-repro

This is a minimal reproduction of the issue occuring when adding JSON data to Vercel environment.

Behaviour

If I add a JSON string to my Vercel environment and pull it via vc env pull, certain characters are escaped (https://github.com/zeit/now/blob/f4d86cb9df757d1154a43549290b6d4a22b55caf/packages/now-cli/src/commands/env/pull.ts#L75) in the resulting file. This makes the resulting JSON invalid.

I was also able to produce this behaviour with https://github.com/zeit/next.js and any node-script using https://github.com/motdotla/dotenv.

Steps to reproduce

CRA

$ vc # link to a project
$ vc env add REACT_APP_DEMO development < demo.json
$ vc env pull

I've added 2 examples of what this behaviour might result in:

1. I'm trying to parse the REACT_APP_DEMO environment variable in App.js which fails.
2. I'm rendering the REACT_APP_DEMO environment variable in App.js which displays multiple \.

dotenv

$ node -r dotenv/config -e "JSON.parse(process.env.REACT_APP_DEMO)"

Running this will show the error.
