// We are using ascii85 as a way save on storage. Also, note that
// the space delimiter we are using is a bit of an abuse since in
// normal cases ascii85 will skip over it, but since we are using
// after encoding and before encoding, it shouldn't be an issue.

// Fields are broken down to facilitate unit testing.
