Nothing is that easy :-)

You have -- thanks. I'll do some reading before making any more noise in
this vein. And yet, from what you say, it sounds like there is still
evidently a gotcha, namely that one must choose in advance between two
different worlds: UTF-8 and ISO 2022 (e.g. Latin-1, etc, with C1 controls).
So if the host uses UTF-8 but I am using a VT320 (or emulator), or the host
uses ISO 2022 with C1 controls and my emulator is switched to UTF, there
will be trouble. But that's not so bad, since we must do this now anyway
prior to making connections to systems that don't use ISO 2022, or that use
PC code pages (etc) on the wire.

Will do -- I didn't notice these coming in as new pages to the International
Register but maybe I missed it.

You've been very helpful, and hopefully we'll have it sooner thanks to your
pointers. Thanks again!
