It may be worth trying without it (i.e. treat "surrogateescape" as equivalent to "strict" initially), and seeing how you go. The main purpose of surrogateescape in CPython 3 is to recreate the "arbitrary 8-bit data round trips work on POSIX" aspect of CPython 2, which doesn't apply in exactly the same way on Jython. Compared to the 8-bit vs 16-bit str discrepancy that exists in Python 2, "surrogateescape is equivalent to strict" seems like a relatively small discrepancy in behaviour.

That would totally break the email package.

It would of course be possible to rewrite email to not use surrogate escape, but it is a seriously non-trivial undertaking.
