Possibly? I don't know much about how these things happen, standards-wise.

Right. If there's ever a newer, widely supported compression format that did
the same thing, that would work too.

Good to know, thanks. I'll make it optional and let the implementation
assume application/zip unless otherwise specified, then.

The manifest probably has to be ASCII (using quoted values like %20 for
spaces etc), sorry about not specifying that.

The UTF-8 default is for any other file in the zip, like JS or CSS, or even
HTML files, should that be useful.

Percent-escaping would be my initial suggestion, but I don't know enough
about any potential issues here if we choose to go that route. I agree that
it needs to be defined, though.
