The base encoding is not yaml, it's json. I need to repurpose strings that
begin with a ! & or *. So in the rare case that an actual json string begins
with one of those, I need to escape it. I do that by putting a '.' in front.
Then I make the rule that in JSYNC, a '.' at the start of a string is
removed. Therefore I need to encode the string '...' as "....". That's a
simple rule. I could make things more complicated by saying I only remove a
leading '.' if it comes before a ! & or *, but that seems a little too
precious to me.

Make sense?

Single quotes are an option, but I would only add them at the start, like in
"'!!!" and "!type '&content".

Hmm, I don't like the ' next to ". Very hard to read. ".!!!" and "!type
.&content" read better.
