JSON is UTF-8, so you're at the mercy of the base64 gods there.

How about using HTTP metadata?

res.setHeader('content-disposition', 'attachment; filename=MyFile');

Or if it's custom metadata, res.setHeader('x-my-metadata', 'value');

If you need to send multiple files, perhaps send a zip or tar of the files. 
Browsers have no support for saving multiple files.
