The Tcl 8 ship has sailed long ago. Tcl 9 is preparing to cast off. Last
change to argue about its I/O defaults.

It seems reasonable to me to have an backwards-compatible
encoding/decoding behaviour. I hope it will not be the default (and yes,
I also have a bigger code base to migrate) but that is not decided by
me.

But beside the question of what the defaults are there are enough open
questions with respect to Tcl 9 I/O and Unicode. There are even TIPs
(don't agree with 652, to say). Perhaps better those are discussed?
