                   ^^^^^^^^^

That's interesting. If this happens when you *omit* squeakToUtf8 then 
it's already being encoded:

	'äs' squeakToUtf8 asByteArray hex => 'c3a473'

So 16rC3 16rA4 are the correct values for utf8-encoded 'ä'.

Basically yes, but only if your input isn't already encoded. Whether 
that's the case I don't know, you might check with the JSON library author.
