The PEP is simple enough that you can simulate its effect by manually computing
the resulting unicode string for a hypothetical broken filename. Several people
have already done so in this thread.

According to some messages, it seems Java and Mono actually use this kind of
workaround. Though I haven't checked (I don't use those languages).

to be able to turn arbitrary byte sequences into unicode strings and back, just
set your encoding to iso8859-15. That already works
That doesn't work at all. With your proposal, any non-ASCII filename will be
unreadable; not only the broken ones.
