The third is to make utf-8 the default. I believe this *is* the proper
long term solution and both options are contrary to this.
I believe that this is what I want for myself even on Windows.
I believe utf-8 is the default or only storage by cross-platform
international programs (certainly the ones I use).

(3) In 3.3, if the default is used and it is not utf-8, add a warning
that the default will become utf-8 always in 3.4. Actually, I would like
a PendingDeprecationWarning in 3.2.1 if possible.
