Overall the control flow here is a bit tricky to follow. I'm not sure if
a real loop condition would help or make it worse.

I'm confused by the asymmetry here. Quoted strings can start with
unicode quotes, but internally can only have ascii '"'? Is this
documented somewhere?

So if there is no quote, we skip the part after the ':'? I guess I
probably missed something because that doesn't sound like the intended
behaviour.
