Message:

owl_new_sv: Escape non-utf8 strings before erroring with them.

Sending known non-utf8 text back into other code is just a bad
plan. In particular, multiline error messages become admin messages,
which results in their bodies getting sent to perl, which calls
owl_new_sv, and we would recurse infinitely.
