Even if you could read MIME multipart directly using XHR, to get a document
complete with its attachments, you'd end up with binary (non-Unicode)
strings in your Javascript.

Ecma-262 says that Strings don't have to be valid Unicode. However CouchDB
requires attachment uploads to be base64-encoded. Would I be right to say
this is because of a JSON restriction, rather than a Javascript one?

CouchDB dodges this at present, since you can't download a document together
with its attachments. I don't suppose that much attachment processing takes
place in Javascript anyway; in normal cases the Javascript creates a URL
from the attachment name, which the user clicks on to download or view the
attachment, without JS ever seeing the body.
