This is a valid concern, but on a higher-level.

Jevko leaves whitespace handling not to clients, but to formats built on Jevko which would be the thing the clients typically use (rather than plain Jevko). Such formats of course should be clearly specified, which is something I hope to get around to soon.

I already have a good candidate format for specifying first, which has 2 implementations:
