compatibility (Python, C++, Go, ...): should newlines (and whitespace in general) in base64 be allowed? (for byte fields in JSON encoding)

[Nicolas Hillegeer]

In the protocolbuffers-go we received a bug (https://github.com/golang/protobuf/issues/1626) for our protojson implementation not accepting strings with whitespace (specifically "\n" in this case) in them.

I think I verified that the C++ implementation also doesn't accept them (see my last comment on the issue). We prefer to stay compatible to C++ as much as possible. So the question is: should this be allowed?

Thanks,
