uescape: also encode non-printable char under 128
We were assuming everything under 128 was printable ascii, but there are a lot
of control characters in that range that can't simply be included in json and
other targets. We forcibly encode everything under 32, because they are either
control char or oddly printable (like tab or line ending).
We also add the hypothesis-powered test that caught this.
