It's not impossible (I think), but is messy. Some are strongly against. 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. --David ___ Python-Dev mailing list [email protected] https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
